Albert Barnes Commentary Jeremiah 11:18

"And Jehovah gave me knowledge of it, and I knew it: then thou showedst me their doings." — Jeremiah 11:18 (ASV)

Rather, gave me knowledge of it, and I knew it. Jeremiah shows (Jeremiah 11:18–23), that the general conspiracy of the people against Yahweh and the special plot against himself was revealed to him by God.
