Charles Ellicott Commentary Jeremiah 23:14

"In the prophets of Jerusalem also I have seen a horrible thing: they commit adultery, and walk in lies; and they strengthen the hands of evil-doers, so that none doth return from his wickedness: they are all of them become unto me as Sodom, and the inhabitants thereof as Gomorrah." — Jeremiah 23:14 (ASV)

They commit adultery, and walk in lies ... —The union of the claim to prophesy in the name of Jehovah with these flagrant breaches of His law was more hateful in the prophet’s eyes even than the open recognition of Baal. In the terrible language of Isaiah (Isaiah 1:10), prophets and people had become like the dwellers in the cities of the plain. Here, also, the language of Deuteronomy (Deuteronomy 29:23; Deuteronomy 32:32) probably influenced that of the prophet.
