John Gill Commentary Jeremiah 23:12

"Wherefore their way shall be unto them as slippery places in the darkness: they shall be driven on, and fall therein; for I will bring evil upon them, even the year of their visitation, saith Jehovah." — Jeremiah 23:12 (ASV)

Wherefore their way shall be to them as slippery [ways] in the darkness Their course of life may fittingly be compared, and in the issue will prove to be like a man walking in a dark night without any lamp or lantern to light him, and in a slippery way, scarcely able to stand upon his legs, and cannot see to pick his way, nor where to step next, which is very uncomfortable and dangerous; such are blind leaders of the blind, and both in danger of slipping and falling into a ditch, (Matthew 15:14).

they shall be driven on, and fall therein; hurried on by Satan and their own lusts, in their sinful ways to their ruin; or forced on into captivity and destruction; their enemies and the just judgments of God pursuing them, like a man pursued by others in a dark and slippery way; who cannot stand to feel his way, but is obliged to go on, though he can scarcely keep upon his legs, and knows not where to set his foot next; see (Psalms 35:6).

for I will bring evil upon them: the evil of punishment, which is from the Lord; as sword, famine, pestilence, or captivity:

[even] the year of their visitation, says the Lord: the precise and exact time appointed by the Lord to visit them in a way of judgment for their iniquities; which was a set time that would certainly come, and they could not escape; and which may not only respect the time of the Babylonish captivity, but the destruction of the Jews by the Romans, which was the time of their visitation, (Luke 19:44).
