Contradiction with Genesis 18:32
This verse shows God willing to spare Sodom if ten righteous are found, while Jeremiah 5:1 suggests not even one righteous can be found in Jerusalem.
Genesis 18:32: And he said, Oh let not the Lord be angry, and I will speak yet but this once: Peradventure ten shall be found there. And he said, I will not destroy [it] for ten's sake.
Contradiction with Isaiah 1:9
This verse implies there is a remnant of righteous people, contrasting Jeremiah 5:1's assertion that none can be found.
Isaiah 1:9: Except the LORD of hosts had left unto us a very small remnant, we should have been as Sodom, [and] we should have been like unto Gomorrah.
Contradiction with Ezekiel 22:30
God seeks someone to stand in the gap to prevent destruction, unlike Jeremiah 5:1, which indicates an inability to find even one righteous person.
Ezekiel 22:30: And I sought for a man among them, that should make up the hedge, and stand in the gap before me for the land, that I should not destroy it: but I found none.
