John Gill Commentary Ezekiel 33:15

"if the wicked restore the pledge, give again that which he had taken by robbery, walk in the statutes of life, committing no iniquity; he shall surely live, he shall not die." — Ezekiel 33:15 (ASV)

If the wicked restore the pledge
His neighbour's raiment, which he has taken as a pledge for money lent him; and which, according to the law, was to be restored before sunset, (Exodus 22:26Exodus 22:27) which wicked men did not attend to; but when such a man is brought to a sense of his wickedness, and repentance for it, as an evidence of it he would restore the pledge.

and give again that he had robbed ;
to him whom he had robbed; as a thief was obliged to do, four or five fold, according to the law, (Exodus 22:1) , and which, when a man did voluntarily, from the convictions of his own mind, and not by force of the civil magistrate, it was a sign of true repentance; see (Luke 19:8) .

and walk in the statutes of life ;
the rule of life and conversation, and to the keeping of which the promise of long life is annexed; and which preserve persons from dying a shameful death by the hand of the civil magistrate; statutes, which, if a man do, he shall live in them; see (Ezekiel 20:11) .

without committing iniquity ;
not living entirely without sin, which the best of men do not; but without committing grosser sins, as before; and without making a trade of sinning, and living in it.

he shall surely live, he shall not die ;
he shall live comfortably now, and happily hereafter; he shall live a spiritual life, and not die the second death.
