Deuteronomy 18:9 Commentary: The Danger of Learning Abominations
Hebrew · 8 what the commentators say
Meaning in one sentence
Deuteronomy 18:9 warns Israel not to learn the detestable practices of the Canaanites.
Research Summary
- Meaning: Israel must not adopt the religious practices of Canaan because those practices are abominable to Yahweh and defile the land.
- Key words: “Learn” (לָמַד, lamad), a process of acquiring knowledge or skill, here explicitly connected to imitating. “Abominations” (תּוֹעֵבַה, to’evah), practices ritually and ethically revolting to God.
- Main debate: Whether “learn” prohibits even intellectual study or only study aimed at practice; most commentators (Jarchi, Calvin) allow knowing the practices to recognize their evil but forbid adopting them.
- Theological theme: Grace precedes command; God gives before he prohibits. The land is a gift that must be kept holy through separation from pagan worship.
- Best use: As a warning against gradual spiritual contamination and a call to intentional, wholehearted loyalty to God.

Scholars' Consensus
The commentators agree that Deuteronomy 18:9 serves as a critical boundary marker for Israel's identity. Calvin notes the human proneness to imitate bad examples, especially when entering a foreign land, the very situation Israel faced. Gill emphasizes that the land itself was a gift, making the command an expression of gratitude: what God gives freely must not be defiled. Matthew Henry is blunt: it seems impossible that a people so blessed with divine institutions would be drawn to Canaanite brutishness, yet they were in danger. The Cambridge Bible connects this verse to the larger unit on prophets (vv. 9, 22), showing that God provided true prophecy precisely because Israel must not rely on heathen divination. Keil and Delitzsch see the prohibition as part of God's ongoing revelation: the law alone would not suffice; Israel would need prophets to guide them through national changes without resorting to Canaanite practices. All agree that the word abominations signals practices God hates, child sacrifice, divination, sorcery, and that the command not to learn them targets a gradual, progressive contamination. The Israelites were not simply to avoid these acts; they were to refuse even the process of learning them.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: God commands Israel not to adopt the religious practices of the Canaanites, which He calls abominations, because those practices define the nations He is driving out.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Meaning of 'learn' (לָמַד) | The verse forbids learning in order to practice the Canaanite religious customs. Commentators agree that the emphasis is on imitation, not mere knowledge. | Some (e.g., Jarchi as cited by Gill) allow learning to understand their corruption and to teach children, while others argue that any familiarity risks contamination. The difference is about whether intellectual exposure without practice is permissible. |
| Scope of 'abominations' | The practices listed in verses 10, 11 (child sacrifice, divination, sorcery, necromancy) are clearly condemned. All traditions treat these as permanently forbidden. | Traditions differ on whether other cultural practices not listed (e.g., modern forms of fortune-telling or syncretistic worship) fall under the same category. Some apply a broad principle of avoiding anything that displaces trust in God; others limit the prohibition to the specific practices. |
| Application to Christians today | Christians universally agree that the verse teaches separation from idolatry and pagan worship. The principle of not imitating the world's religious practices is accepted. | The practical extent of separation varies: some hold that believers should avoid any direct contact with non-Christian religious practices (e.g., studying other scriptures), while others emphasize engaging culture critically without adopting its values. |
Historical & Cultural Context
Deuteronomy 18:9 opens a unit (through v. 22) that deals with leadership in the land, first priests and Levites (vv. 1, 8), then prophets. Verse 9 marks a sharp pivot: before discussing true prophecy, Israel must understand what they are to reject. The surrounding context (Deuteronomy 12, 18) repeatedly warns against adopting Canaanite religious customs. The land itself had been defiled by these practices, as Leviticus 18:27 states: “for the men of the land that were before you had done all these abominations, and the land became defiled.”
Calvin observes that people entering a foreign country readily adapt to its manners. This is why God specifically commands Israel to beware of catching “infection” from the Canaanites. The list that follows in verses 10, 11, child sacrifice, divination, sorcery, necromancy, represents the worst of ancient Near Eastern religion. Child sacrifice to Molech was a known Canaanite and Phoenician practice, condemned strongly in Leviticus 18:21 and Deuteronomy 12:31. Divination and sorcery were attempts to control or manipulate spiritual forces, in direct opposition to trusting Yahweh.
Lange's commentary notes that the word for “soothsayer” (qosem) puns on “liar” (kozev), suggesting the deceptive nature of these arts. The land of Canaan was not neutral territory; it was thick with religious practices that Israel was to expel and replace with pure worship. The command is given as the people stand on the brink of entering the land, a moment of decision that would shape their entire national life.
Textual Notes
The supplied sources note no significant textual variants for Deuteronomy 18:9. The Hebrew text is stable across traditions. The verse’s structure, a temporal clause followed by a prohibition, is consistent with standard Deuteronomy style.
Reception History
Deuteronomy 18:9 has been read throughout church history as a warning against cultural assimilation. Early church writers such as Justin Martyr and Tertullian used it to argue against Christians participating in pagan festivals. In the medieval period, commentators like Rashi emphasized the necessity of knowing the evilness of Canaanite practices in order to teach children to avoid them. Reformation-era writers (Calvin, Luther) saw this command as a call to pure worship, free from human inventions. More recently, the verse has been applied to contemporary questions of how Christians engage a pluralistic society, balancing the need to be in the world without being of it. The overarching theme has remained constant: God’s people are to learn only from Him, not from the practices of those who do not know Him.
Preaching This Verse
Three-point outline
- The Gift Before the Command: The land is given by Yahweh (v. 9a). This reminds Israel that their identity rests on grace, not merit. The command flows from that grace.
- The Prohibition of “Learning”: The verb “learn” (lamad) implies gradual mastery through repeated exposure. God does not merely forbid the acts; he cuts off the pathway that leads to them.
- The Contrast with Holiness: Verse 13 follows: “You shall be blameless with Yahweh your God.” The prohibition is set against the call to wholehearted loyalty, tamim, complete or perfect.
Five-point outline
- Entering the Land (v. 9a): The promised gift becomes the place of testing.
- The Negative Command (v. 9b): “You shall not learn to imitate the abominations.” The infinitive “to do” specifies the intended outcome of the learning.
- The Specific Practices (vv. 10, 11): Child sacrifice, divination, sorcery, each is a perversion of worship and knowledge.
- The Theological Reason (v. 12): These things are an abomination to Yahweh, and they are why the nations are being driven out.
- The Positive Call (v. 13): Blamelessness, not bare avoidance, is the goal.
Illustration hooks
- Moving day: When a family relocates to a new country, children often pick up the local language and customs quickly, including bad habits. That is the kind of gradual assimilation Moses warns against.
- Online algorithms: A person does not decide overnight to embrace harmful ideologies. Algorithms feed small doses over time. The command “do not learn” addresses the feeding process itself.
- Peer pressure in adolescence: Teens often adopt the values of their friend group without noticing the shift. The verse invites vigilance about what we expose ourselves to regularly.
Questions your congregation is asking
- Does this mean I cannot study other religions or read about them? (The key is the verb “to do”, learning in order to imitate and practice.)
- How do we protect our families from cultural influences that conflict with our faith?
- What counts as an “abomination” today, is it only the specific practices listed, or does the principle extend to modern paganism?
Leading a Discussion
This verse comes at a critical moment: Israel is about to enter a land filled with customs that directly contradict their covenant with Yahweh. The command is deceptively simple: do not learn to do what these nations do. As you discuss, notice that the prohibition targets learning, a process, not just an act. The group can reflect on how gradual exposure shapes our desires and actions.
Discussion questions
- Read verses 9, 14 aloud. What does the word “abomination” (or “detestable”) communicate about God’s view of these practices?
- Why do you think God frames the command around “learning” rather than simply “doing”? What does that reveal about the danger of exposure?
- Calvin said people readily adopt the customs of a foreign land. In what ways do Christians today absorb the values of the surrounding culture without noticing?
- How does the gift of the land (“which Yahweh your God gives you”) change the tone of this command? Does grace or law come first here?
- Verse 13 says “You shall be blameless with Yahweh your God.” How does the prohibition in verse 9 connect to that positive call?
- What are specific “abominations” in our own society that Christians might tolerate or learn to accept?
- How can we guard our hearts and homes from learning to imitate what God calls detestable, without withdrawing from the world entirely?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Calvin's Commentaries Reformed 1564
Calvin emphasizes that God's warning arises from humanity's natural tendency to copy foreign customs, especially in a new land. He defines "having other gods" specifically as mixing true worship with profane practices, insisting the purity of religion demands removing every human invention that corrupts simple faith.
Cambridge Bible for Schools and Colleges Anglican 1880
The Cambridge Bible Schools commentary stresses that Deuteronomy's law of the prophet forms a unified, natural contrast to foreign divination. It defends the passage's integrity against critics and notes that the test of a false prophet by non-fulfillment mirrors how Jeremiah himself relied on events to verify his word from the Lord.
Geneva Bible Notes Reformed 1599
The Geneva note stresses that Israel was to learn nothing from the pagan nations they were replacing. Entering the land God gave them did not mean adopting its previous inhabitants' customs; God specifically forbade even learning their detestable practices.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that God gave Israel the land as a pure gift, not something they earned, and he sees it as a type of heaven. He allows that Israel could study the nations' abominations to understand their corruption and warn their children, but they must never copy those practices, only loathe them.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB highlights that despite God's direct command to avoid the abominable practices of Canaan, those nations, especially the Philistines, remained a persistent snare to Israel. Their divinations and superstitions constantly tempted the people, making the prohibition a practical, ongoing struggle rather than a past event. This sets up the need for a greater prophet.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch argue that the promise of a prophet in Deuteronomy does not refer to one single prophet or directly to the Messiah alone, but rather to a continuing line of prophets. The context of sorcery and the later rules for testing prophets show that God would raise up many such spokesmen as mediators when the people needed them. The phrase "like unto me" points to the prophet's role as a mediator like Moses, not necessarily to an identical mode of revelation.
Lange's Commentary Reformed 1857
Lange underscores that the prophetic office is God's answer to Israel's need for ongoing divine revelation after Moses. Unlike the surrounding nations who turn to dark arts and divination, Israel is promised a line of prophets who, like Moses, speak God's words directly. This prophetic order forms the living, authentic word that guides and corrects the people.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry is astonished that Israel, so blessed with divine institutions, could ever be tempted by the brutish, barbarous customs of the Canaanites they conquered. He specifies child sacrifice to Moloch, an idol representing the sun, and divination arts that attribute God's power to the devil as the particular abominations forbidden.
