Albert Barnes 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)

Every word denotes the certainty of their fall. Their path is like slippery places in darkness; and on this path, they are pushed with violence. External circumstances assist in urging on to ruin those who choose the path of vice.
