And thine abominations - “Even thy abominations.” The prophet sums up the three charges against Judah, namely, spiritual adultery, inordinate eagerness after idolatry (see the note at Jeremiah 5:7 note), and shameless participation in pagan orgies.
In the fields - “in the field,” the open, unenclosed country (see Jeremiah 6:25; Jeremiah 12:4).
Wilt thou not ... once be? - “Or, how long yet ere thou be made clean!” These words explain the teaching of Jeremiah 13:23. Repentance was not an actual, but a moral impossibility, and after a long time Judah was to be cleansed. It was to return from exile penitent and forgiven.
