Deuteronomy 23:18 Commentary: The 'Price of a Dog' and Holy Vows

Deuteronomy 23:18 sits within a cluster of laws about purity in the camp and worship. Verses 17, 18 directly address religious prostitution. In Canaanite religions (especially the cult of Astarte), women and men would serve as cult prostitutes. Their sexual acts were considered acts of worship, and the payments they received were offered to the deity. Keil and Delitzsch note that the Hebrew terms kedeshah (female) and kadesh (male) designate persons 'consecrated' to this degrading service. The Israelites had encountered this practice in Canaan even before the conquest (Genesis 38:21).

Herodotus describes similar practices in Babylon, where every woman once in her life sat in the temple of Mylitta to offer herself to a stranger. Adam Clarke mentions that the Temple of Venus Melytta kept public prostitutes whose gains supported the temple. The law in Deuteronomy cuts against this entire worldview: the God of Israel does not need, and cannot accept, offerings that come from violating His own moral order.

This command also connects to the broader theme of holiness woven through Deuteronomy 23. The camp must be holy because Yahweh walks among His people (v. 14). Accepting immoral earnings would make the worship space unclean, as if inviting the very sin God abhors into His presence. The verse immediately follows a prohibition against having any prostitute or sodomite among Israel (v. 17). Not only must the people themselves be free from such practices, but the offerings they bring must also be pure in origin.

The phrase 'for any vow' ties the rule to voluntary offerings. In Israel, vows were taken seriously (v. 21). But even a solemn vow could not sanctify tainted money. The means by which a person acquired the offering mattered to God. Worship is not a transaction where God accepts anything we bring; the character of the giver and the source of the gift reflect on the holiness of the altar.

The supplied sources note no significant textual variants for Deuteronomy 23:18. The Hebrew text is stable across manuscripts. Differences in English translations (e.g., KJV 'price of a dog' vs. BSB 'wages of a male prostitute') reflect interpretive decisions rather than textual variants.

From the early church through the Reformation, Deuteronomy 23:18 was used to maintain purity in worship and church finances. The principle that offerings from sinful sources are unacceptable influenced church discipline: some councils refused donations from prostitutes, actors, and others in disreputable trades. In the medieval period, this verse was cited to argue against simony (buying church offices).

Reformation commentators like Calvin and the Geneva Bible notes emphasized that God will not be bribed by gifts from wickedness. Later, this verse informed Christian debates about tithing on 'unclean' money. It has also been used pastorally to counsel new believers who feel their past earnings are tainted, pointing them to the grace that transforms the giver even as it honors the principle of holy offerings.

Three-point outline

1. The problem of ill-gotten gains. Israel was surrounded by cultures that used temple prostitution to fund their religions. God forbids any such income from being offered to Him. Worship cannot be financed by sin.
2. The meaning of 'the price of a dog'. Interpreters disagree: some take 'dog' literally (the sale price of an unclean animal); most take it figuratively for the wages of a male prostitute (a 'dog' being a contemptible, shameless person). Both readings reinforce the same point: the money is defiled by its origin.
3. Holiness at the center. Because Yahweh dwells among His people, everything brought into His house must reflect His character. This principle guards against any attempt to separate our offerings from how we live the rest of our lives.

Five-point outline

1. Background: Canaanite religious prostitution.
2. The prohibition: no offering from prostitution accepted.
3. The debate: literal dog or male prostitute?
4. The reason: 'both are an abomination to Yahweh your God.'
5. Application: God cares about the source of our gifts, not just their size.

Illustration hooks

• A church that unwittingly accepted a large donation from a gambling operation. Members debated: can God use tainted money for good? This verse suggests the source matters.
• A person who tries to 'balance the scales' by giving generously to God while living dishonestly all week. The offering itself can become a cover, not a cure.
• The awkward feeling of accepting a gift from someone whose income relies on exploitation. Deuteronomy 23:18 puts words to that unease.

Questions your congregation is asking

• Does this mean I can never give money I earned in a sinful way before I became a Christian?
• How do I know if my own earnings are 'clean' enough for God?
• Should a church ever refuse a donation? If so, on what basis?

This verse forces us to think about the connection between how we earn our money and how we use it in worship. The Israelites faced a clear case: income from prostitution and male prostitution. But the principle extends further. Money is never neutral; it carries the fingerprints of how it was obtained. As you discuss, hold the tension between grace (God receives repentant sinners) and holiness (God does not let sin define the worship space).

Discussion questions

1. Read Deuteronomy 23:17, 18. What do these verses reveal about the religious practices of the nations around Israel?
2. Why do you think God gave this specific command? What problem was it addressing?
3. The word 'abomination' (Hebrew to'evah) is strong. Why is this language used for prostitution earnings?
4. Interpreters disagree on 'price of a dog', some say literal (dog sale), others figurative (male prostitute). How does each reading affect the meaning of the verse?
5. Does this law apply only to the Old Testament temple, or does it set a principle for Christian giving? Explain.
6. How can we examine the source of our own income and offerings without falling into self-righteousness or anxiety?
7. In what ways might modern Christians unintentionally bring 'unclean' offerings into worship?
