Deuteronomy 2:19 and 2:37 forbid Israel from invading or seizing Ammonite land, because Yahweh assigned that land to the descendants of Lot. Judges 11:32 has Jephthah pass over to fight the Ammonites and slaughter them, and Jeremiah 49:2 has Yahweh promising Rabbah will become 'a desolate heap, and her daughters shall be burned with fire.' The Ammonite protection clause and the destroy-Ammon oracles can't both stand at face value.
Proposed answers
People have answered this in several ways; GEBible presents them as equal peers.
Do not fight against them or take their land.
And when thou comest
nigh over against the children of Ammon, distress them not, nor meddle with
them: for I will not give thee of the land of the children of Ammon any
possession; because I have given it unto the children of Lot for a
possession. Deuteronomy 2:19
Only unto the land of the children of Ammon thou camest not ... nor unto
whatsoever the LORD our God forbad us. Deuteronomy 2:37
(However, we avoided the land of the Ammonites all along the Jabbok River and the towns
in the hill countryall the places the LORD our God had commanded us to leave alone. v.37 from the New Living Translation)
19When you come near the border of the children of Ammon, don’t bother them, nor contend with them; for I will not give you any of the land of the children of Ammon for a possession, because I have given it to the children of Lot for a possession.”
37Only to the land of the children of Ammon you didn’t come near: all the banks of the river Jabbok, and the cities of the hill country, and wherever Yahweh our God forbade us.
2Therefore behold, the days come,” says Yahweh, “that I will cause an alarm of war to be heard against Rabbah of the children of Ammon; and it will become a desolate heap, and her daughters will be burned with fire: then Israel will possess those who possessed him,” says Yahweh.

How critical scholarship weighs this: Leans toward a genuine contradiction
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
The tension parallels the Moabite case. Deuteronomy 2:19 forbids Israel to harass or seize Ammonite land "because I have given it unto the children of Lot for a possession," and 2:37 confirms Israel avoided Ammonite territory along the Jabbok. Judges 11:32 then has Jephthah cross over "to fight against the children of Ammon" with Yahweh delivering them into his hand, and Jeremiah 49:2 has Yahweh promise that Rabbah "shall be a desolate heap, and her daughters shall be burned with fire." The protection clause and the destruction oracles cannot both stand at face value.
The apologetic harmonization mirrors the Moab argument. Deuteronomy 2:19 is a one-time wilderness travel directive constraining Israel's march to Canaan, not a permanent treaty of non-aggression; Judges 11 and Jeremiah 49 are later responses to Ammonite aggression. Jephthah's war is, on this reading, defensive—Ammon presses a territorial claim to the land between the Arnon and the Jabbok (Judg 11:13), and the diplomatic exchange in Judges 11:14-27 frames Israel's action as a response to Ammonite encroachment rather than a violation of a Lot-grant homeland. Jeremiah's oracle is then judicial: a response to Ammon's idolatry (the cult of the national god) and its seizure of Israelite territory after the fall of the northern kingdom. Block and Butler handle the Judges material this way, and the chronological framework genuinely covers most of the surface narrative—the Deuteronomic prohibition concerns the wilderness itinerary, whereas Jephthah and Jeremiah address centuries-later hostilities. To the extent the question imagines a single static rule for "how the Ammonites should be treated," that reading flattens a layered textual history, and the chronological case dissolves much of it.
What the chronology does not dissolve is the land-grant theology. The structure of the Deuteronomic clause is identical to the Moabite one: the perfective grant-language "I have given" (Hebrew *natatti*), grounded in Lot-kinship, with no stated condition or expiry. The grant is framed as Yahweh's own apportionment of the earth, parallel to the Edom (Esau) and Moab notices in Deuteronomy 2, and the Deuteronomist offers no clause making it revocable on the recipients' conduct. Jeremiah 49:1 does not merely announce punishment—it attacks the premise of the grant: "Hath Israel no sons? hath he no heir? why then doth their king inherit Gad, and his people dwell in his cities?" The rhetorical questions imply that the children of Lot have no legitimate title to the territory in question, and that Gad's land rightfully belongs to Israel. A textual note is in order here: the consonantal *mlkm* admits two readings, vocalized either as *malkam* ("their king," so KJV) or as *milkom* (the Ammonite national deity Milcom, so NRSV, ESV, and most modern editions, supported by the parallel "his people" and the LXX's treatment). The wordplay is almost certainly deliberate—king and god collapse into one—but the Milcom reading is a recognized translation crux rather than a settled datum, and the argument here does not depend on which vocalization one adopts. Either way, the verse is a reversal of the Deuteronomic land theology, not just a penalty for misbehavior. Lundbom and Holladay both flag the tension in their treatments of Jeremiah 49.
The critical-scholarship reading is the same as for Moab: two traditions about Ammon coexist in the canon—a "children of Lot" tradition treating them as protected kin (cf. the Genesis 19 origin etiology) and an "enemy nation" tradition subjecting them to *herem*-style judgment—reflecting different periods and theological frameworks. The protective Deuteronomic stance likely reflects a period of relatively stable relations and a theology that read the Trans-Jordanian neighbors as recipients of their own divine allotment; the prophetic oracles reflect later conflict, including the post-722 Ammonite expansion into vacated Gadite land that Jeremiah 49:1 protests. Weinfeld and Tigay note that the varied biblical stance toward the Trans-Jordanian neighbors is itself a product of this multi-tradition layering, and Carroll reads the oracle as part of the prophetic oracles-against-the-nations collection rather than a coherent legal supplement to Deuteronomy.
The harmonization patches the surface narrative if one grants that Yahweh's land grants are revocable on the recipients' conduct. But Deuteronomy 2:19 includes no such condition; it is an unconditional "I have given" clause. To invalidate it later requires precisely the theological revision Jeremiah 49:1 performs ("Hath Israel no heir?"), and that revision is itself the seam.
Where the critical reading lands: partially harmonizable by chronology, with a genuine residual contradiction over the irrevocability of the Lot land-grant, carrying a clear redactional fingerprint.
