Jeremiah 9:5

Deceive. — The word is commonly translated, as in the margin, mock. (So in 1 Kings 18:27; Judges 16:10; Judges 16:13; Judges 16:15.) The context here shows, however, that the kind of mockery is that which at once deludes and derides; and as the former meaning is predominant, the text of the English version had better stand as it is.

To commit iniquity. — Literally, to go crookedly, or, in the strict sense of the word, to do wrong.
