Deuteronomy 23:3-6

“An Ammonite or a Moabite shall not enter into the assembly of Yahweh; even to the tenth generation shall none of them enter into the assembly of Yahweh forever, because they didn’t meet you with bread and with water on the way when you came out of Egypt, and because they hired against you Balaam the son of Beor from Pethor of Mesopotamia, to curse you. Nevertheless, Yahweh your God wouldn’t listen to Balaam; but Yahweh your God turned the curse into a blessing to you, because Yahweh your God loved you. You shall not seek their peace nor their prosperity all your days forever.”

This passage is part of Moses' farewell address to the Israelites on the plains of Moab, just before they are about to enter the Promised Land. He is reiterating laws and instructions given by God, aiming to remind them of their history and covenant responsibilities as they prepare for a new chapter.

Then — the setting

The decree in Deuteronomy 23:3-6 stems from specific historical grievances that occurred during Israel's forty-year wilderness journey after leaving Egypt (around 14th-13th century BCE). As Israel approached the land of Canaan, Moab and Ammon, two Transjordanian kingdoms related to Israel through Lot (Abraham's nephew), actively opposed their passage. Moab's King Balak hired the prophet Balaam to curse Israel, and both nations withheld basic provisions like bread and water, which were crucial for the traveling multitude. These acts were seen as a betrayal by kinsmen and a direct affront to God's care for Israel, leading to a long-lasting exclusion from full participation in Israelite communal life.

Across the Testaments

This passage is from the Old Testament, laying down a specific legal and social boundary. The New Testament, while not directly repealing this specific decree, shifts the focus from national-ethnic identity to faith in Jesus as the basis for inclusion in God's people. Passages like Galatians 3:28 ('There is neither Jew nor Greek...') emphasize a new kind of assembly where ethnic origin is not a barrier to belonging. However, the underlying Old Testament principle of setting boundaries for those who actively oppose God's people or seek their harm still resonates, though applied in a different, spiritualized context rather than an ethnic one.
