Contradiction with Jonah 3:4
Jonah's prophecy states that Nineveh will be overthrown in 40 days, without condition, contrasting with the conditional nature of Jerusalem's destruction in Jeremiah 26:18 based on repentance.
Jonah 3:4: And Jonah began to enter into the city a day's journey, and he cried, and said, Yet forty days, and Nineveh shall be overthrown.
Contradiction with Ezekiel 18:21
Highlights the potential for a wicked person to turn from their sins and live, presenting a contrast to the implied inevitability of destruction in Jeremiah 26:18.
Ezekiel 18:21: But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die.
Contradiction with 2 Samuel 24:16
Depicts God relenting from sending destruction upon Jerusalem, contradicting the prophetic certainty of Jerusalem's ruin in Jeremiah 26:18.
2 Samuel 24:16: And when the angel stretched out his hand upon Jerusalem to destroy it, the LORD repented him of the evil, and said to the angel that destroyed the people, It is enough: stay now thine hand. And the angel of the LORD was by the threshingplace of Araunah the Jebusite. [Araunah: also called, Ornan]
Contradiction with Isaiah 31:5
Asserts God's defense and protection of Jerusalem, which contrasts with the prophecy of Micah quoted in Jeremiah 26:18 about Zion and Jerusalem facing devastation.
Isaiah 31:5: As birds flying, so will the LORD of hosts defend Jerusalem; defending also he will deliver [it; and] passing over he will preserve it.
Contradiction with Joshua 6:2
Describes the definite destruction of Jericho as commanded by God, contrasting with the conditional aspect of the prophecy in Jeremiah 26:18 based on the people's response.
Joshua 6:2: And the LORD said unto Joshua, See, I have given into thine hand Jericho, and the king thereof, [and] the mighty men of valour.
Contradiction with Numbers 23:19
Emphasizes that God does not change His mind or repent, which could be seen as contradicting the conditional aspect of Jerusalem's fate in Jeremiah 26:18.
Numbers 23:19: God [is] not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do [it]? or hath he spoken, and shall he not make it good?
Contradiction with Zechariah 8:15
Mentions God’s determination to do good unto Jerusalem, which appears contrary to the negative prophecy in Jeremiah 26:18 of Jerusalem's destruction.
Zechariah 8:15: So again have I thought in these days to do well unto Jerusalem and to the house of Judah: fear ye not.
Contradiction with Revelation 3:12
Speaks of God establishing His people as pillars in His temple, seen as contrasting the message of Jerusalem's ruin in Jeremiah 26:18.
Revelation 3:12: Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, [which is] new Jerusalem, which cometh down out of heaven from my God: and [I will write upon him] my new name.
Contradiction with Isaiah 55:11
Expresses the idea that God's word will accomplish what He desires and will not return void, which can be inconsistent with the conditional nature of Jeremiah 26:18's prophecy if the people repent.
Isaiah 55:11: So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper [in the thing] whereto I sent it.
