Scholars' Consensus
Commentators across traditions agree that this verse points to God acting out of His own character, not human merit. The phrase “for his righteousness’ sake” is most often read as God’s covenant faithfulness (Barnes, Calvin, Gill). The verb “was pleased” (חָפֵץ) expresses a settled divine delight. The purpose is to magnify the law (תּוֹרָה), God’s instruction, and make it glorious. There is broad agreement that this divine initiative precedes and contrasts with Israel’s blindness and the judgment that follows in verses 22, 25. Debate centers on whether the “righteousness” refers strictly to God’s attribute, to the Messiah’s righteousness (JFB), or to God’s justice in punishment. But the core consensus stands: God exalts His law because He Himself is faithful.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- God's covenant faithfulness: Barnes, Calvin, and many modern commentators argue that 'his righteousness' refers to God’s own faithfulness to His promises (Psalm 71:16,19).
- Messianic righteousness: JFB and some patristic interpreters see the righteousness as Messiah’s, connecting to Isaiah 42:1 and Matthew 3:15.
- God's justice in punishment: Gill notes that some interpret the verse as God magnifying the law through judgment on the disobedient, supporting law's authority.
What is clear: God is the subject who acts to make His law great and glorious, and this action is grounded in His own righteous character, not human merit.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Meaning of 'his righteousness' | The phrase refers to God's own attribute, His faithfulness, justice, or loyalty to His covenant. | Some (Calvin, Barnes) say it is exclusively God's faithfulness to His promises; others (JFB) see it as including the righteousness of the Messiah, who fulfills the law; a minority read it as God's justice in punishing sin (Gill notes this as a possible interpretation). |
| Identity of the servant in the context | Verse 21 is about God's action toward Israel or toward the ideal servant figure. | Many (Cambridge Bible, Lange) see the servant of 42:1, 4 as the ideal Israel, while the blind servant of 42:18, 20 is the actual nation. Others (some Reformed tradition) take the first servant as the Messiah and the second as Israel. Verse 21 is often taken as God's response to the unfaithful servant nation. |
| Meaning of 'magnify the law', salvation or judgment? | God acts to exalt His instruction and make it glorious. | Some (Wesley, Poole) interpret this as God's patient waiting for repentance to avoid dishonoring the law. Others (Gill) see it as God magnifying the law through punishing transgressors, thus upholding its authority. Still others (JFB, Calvin) see it as ultimately fulfilled in Christ, who honors the law perfectly. |
| Context of exile and judgment | The surrounding verses (22, 25) describe judgment on Israel because of disobedience. | Some (Barnes) argue that verse 21 presents God's original intention to bless, making the judgment more poignant. Others (Keil & Delitzsch) see the verse as part of the indictment, God was pleased to give a great law, yet the people are now plundered. This shapes whether the verse is read as comfort or accusation. |
Historical & Cultural Context
Isaiah 42:21 sits within a larger section (42:18, 25) that rebukes Israel for spiritual deafness and blindness. The people have “seen many things” but not observed, heard but not listened (v.20). The surrounding context describes a nation robbed, plundered, and imprisoned (v.22), the result of their disobedience against the law (v.24). Verse 21 interrupts this indictment to remind readers of God’s original intention: He delighted to give a “great and glorious” instruction. The Hebrew verb “magnify” (יַגְדִּיל, from גָּדַל) means to make great; “make honorable” (יַאְדִּיר, from אָדַר) means to make glorious. Together they exalt the Torah as God’s supreme gift.
Historically, the passage likely addresses the Babylonian exile. God’s law had been given at Sinai with splendor (Deuteronomy 4:6, 8), but Israel’s sin brought the covenant curses (Deuteronomy 28). Yet even in judgment, the prophet shows that God’s purpose was never to abandon His law but to uphold it. Later Christian readers (e.g., JFB) connected this verse to Christ, who “fulfills all righteousness” (Matthew 3:15) and magnifies the law through His perfect obedience and teaching. Both Jewish and Christian traditions agree that the verse underscores God’s unwavering commitment to His own word.
Textual Notes
The Hebrew text of Isaiah 42:21 is stable across manuscripts. A notable variant appears in the Septuagint, which reads “praise” (תודה, todah) instead of “law” (תורה, torah), as Adam Clarke notes. The Dead Sea Scrolls support the Masoretic reading. Some English translations (e.g., Darby) add “in him” after “delight,” reflecting a different division of the verse. None of these variants significantly alter the main interpretive questions.
Reception History
Jewish exegesis has traditionally read this verse as God’s commitment to exalt the Torah despite Israel’s failures. The Targum (Aramaic paraphrase) connects it to Israel’s justification. In Christianity, early patristic interpreters (e.g., Jerome) saw Christ as the one who magnified the law through perfect obedience. The Reformers (Calvin, Luther) emphasized God’s free grace and faithfulness. The Wesleyan tradition (Adam Clarke) focused on God’s delight and mercy. The verse has been used in hymns that celebrate God’s law and in sermons on covenant faithfulness. Across traditions, it remains a touchstone for discussing God’s character and the purpose of biblical instruction.
Preaching This Verse
Three-point outline
- God’s Pleasure in His Own Righteousness, The verse starts with divine delight. God is not coerced; He willingly chooses to act for His name’s sake. This comforts us that God’s plans rest on His character, not our performance.
- The Purpose: Magnifying the Law, God’s action makes the Torah great and glorious. The law is not set aside but honored. This points ultimately to Christ, who did not abolish the law but fulfilled it (Matthew 5:17).
- The Paradox: Judgment Despite God’s Goodness, Verses 22, 25 show that Israel, for all their privilege, experienced exile. God’s goodness does not eliminate human responsibility. The same law that magnifies grace also condemns rebellion.
Five-point outline
- The Lord delights in His people (v.21a).
- He acts for His own righteousness (v.21a).
- He exalts His law as great and glorious (v.21b).
- Yet His people are blind and deaf (vv.18, 20).
- The result: judgment leading to exile (vv.22, 25).
Illustration hooks

Adam Clarke's Commentary Methodist/Wesleyan 1826
He win magnify the law "He hath exalted his own praise" - For תורה torah, the law, the Septuagint read תודה todah, praise.
Barnes' Notes on the Bible Protestant 1832
Barnes argues that God’s delight in His people rests entirely on His own righteous faithfulness to His promises, not on any merit in them. He interprets “magnify the law” as God making the law appear great and honorable by His own steadfast regard for it, rather than referring to the Messiah.
Calvin's Commentaries Reformed 1564
Calvin insists the fault lies entirely with the Jews, not with God. The Lord was willing and eager to deliver them and magnify his law, but they rejected every offer of relief by their own stubborn choice to remain blind. God's readiness to help makes their rejection all the more inexcusable.
Cambridge Bible for Schools and Colleges Anglican 1880
The Cambridge Bible Schools commentary argues that the same "Servant of the Lord" refers to Israel in two different aspects: its ideal calling and its actual, blind and deaf condition. The contrast is not between a false and true servant or between a nation and an individual, but between what Israel was meant to be and what it had become. Israel failed to understand its own history as God's visitation.
Geneva Bible Notes Reformed 1599
The Geneva note stresses that God's willingness to exalt and magnify the Law flows directly from His own righteousness. His honor is at stake in upholding the Law's authority, so He acts not out of bare will but because His righteous character demands it.
Gill's Exposition of the Bible Baptist 1748
Gill applies the verse to God's delight in the believing remnant, not the disobedient nation. God is well pleased with them solely for the sake of Christ's righteousness, not
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB stresses that "his righteousness" refers to God's own righteousness, not Israel's, since they had none. God is well pleased with His Son, who fulfills all righteousness for them, and for His sake He is well pleased with Israel despite their sin. This righteousness also includes God's faithfulness to His promises, which rest on the Messiah's righteousness.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch emphasizes that God gave His people a great and glorious Torah out of His righteousness, meaning not a reward for their obedience but a merciful revelation tied to His saving plan. Israel's tragic condition—robbed, fastened in holes, trapped in prison-houses—stands as a glaring contrast to that gift, showing that they saw much but never truly took it to heart.
Lange's Commentary Reformed 1857
Lange argues that the Servant's gentleness is remarkable only because He could have used great power but chose not to. This deliberate restraint, he contends, rules out Israel or any prophet as the Servant, pointing instead to Christ, who alone fit the description.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry shifts from comforting the faithful to confronting the unbelieving. He identifies these blind and deaf Israelites as a type of those who rejected Christ, comparing them to the evil figs of Jeremiah who were destined for ruin and remain scattered to this day.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley highlights that God withholds the destruction sinners deserve, but not simply from compassion. His patience serves a dual purpose: to give room for repentance, and to protect the honor of His own law and covenant promises from being scorned by those who observe His dealings.
