Who knoweth [if] he will return and repent,.... Which some understand of man, and of his returning and repentance; either thus whosoever he be that knows the ways of repentance, he will return, and God will repent of this evil: which sense is mentioned by Kimchi and Ben Melech: or he that knoweth that iniquity is on him will return and repent; so Jarchi, with which agrees the Targum,"he that knows that sins are in him will return from them, and he shall obtain mercy; and whoever repents, his sins shall be forgiven him;''but rather they are to be understood of God, as some in Kimchi, and paraphrase it, who knows?
perhaps God may return; and this is the sense of Aben Ezra, and seems to be most correct; and to be interpreted, either as carrying some doubt in it; not as if it was questionable whether God will give pardon to repenting sinners, but whether he will at once remove the present affliction and chastisement; which may be thus expressed to check the presumption and awaken the security of the people, and rouse them from their sluggishness and stupidity: or rather as expressive of hope that God would return and change the dispensation of his providence, and repent of the evil he had threatened, or brought upon them; which might be justly grounded upon the character before given of him, and that from the revelation of himself, and the proclamation of his own perfections; see Jon 3:9;and leave a blessing behind him; meaning not behind God himself, as if he was departed, or about to depart, for which there was no great concern, provided he left a temporal blessing with them; but behind the army of the locust, after that had made all the devastation it did: or rather "cause to leave"; stop the locust in its progress, and not suffer it to make a total desolation, but cause it to leave some of the fruits of the earth behind it.
