Jamieson, Fausset and Brown on Ezekiel 18:30-32

30-32. As God is to judge them "according to their ways" (Pr 1:31), their only hope is to "repent"; and this is a sure hope, for God takes no delight in judging them in wrath, but graciously desires their salvation on repentance.

I will judge you--Though ye cavil, it is a sufficient answer that I, your Judge, declare it so, and will judge you according to My will; and then your cavils must end.

Repent--inward conversion (Re 2:5). In the Hebrew there is a play of like sounds, "Turn ye and return."

turn yourselves, &c.--the outward fruits of repentance. Not as the Margin, "turn others"; for the parallel clause (Eze 18:31) is, "cast away from you all your transgressions." Perhaps, however, the omission of the object after the verb in the Hebrew implies that both are included: Turn alike yourselves and all whom you can influence.

from all ... transgressions--not as if believers are perfect; but they sincerely aim at perfection, so as to be habitually and wilfully on terms with no sin (1Jo 3:6-9):

your ruin--literally, "your snare," entangling you in ruin.
