Contradiction with Ezekiel 25:10
This verse predicts that the children of Ammon will be given to the people of the east as a possession, contradicting the restoration promised in Jeremiah 49:6.
Ezekiel 25:10: Unto the men of the east with the Ammonites, and will give them in possession, that the Ammonites may not be remembered among the nations. [with...: or, against the children of Ammon]
Contradiction with Amos 1:13-15
These verses proclaim judgment and destruction upon the Ammonites without mention of restoration, contrasting with the promise of restoring captives in Jeremiah 49:6.
Amos 1:13-15: Thus saith the LORD; For three transgressions of the children of Ammon, and for four, I will not turn away [the punishment] thereof; because they have ripped up the women with child of Gilead, that they might enlarge their border: [ripped...: or, divided the mountains]
Contradiction with Zephaniah 2:9
This verse pronounces that Moab and the children of Ammon will be like Sodom and Gomorrah, a perpetual desolation, which contradicts the idea of bringing back their captivity.
Zephaniah 2:9: Therefore [as] I live, saith the LORD of hosts, the God of Israel, Surely Moab shall be as Sodom, and the children of Ammon as Gomorrah, [even] the breeding of nettles, and saltpits, and a perpetual desolation: the residue of my people shall spoil them, and the remnant of my people shall possess them.
Contradiction with Isaiah 11:14
It suggests that Israel will take over the lands of the Ammonites and others, conflicting with the notion of a returned captivity for Ammon as implied in Jeremiah 49:6.
Isaiah 11:14: But they shall fly upon the shoulders of the Philistines toward the west; they shall spoil them of the east together: they shall lay their hand upon Edom and Moab; and the children of Ammon shall obey them. [them of: Heb. the children of] [they shall lay...: Heb. Edom and Moab shall be the laying on of their hand] [shall obey...: Heb. their obedience]
