John Gill, on Lam 3:35

Out of the mouth of the most High proceed not evil and good? Certainly they do; they come to pass, both one and the other, as God has pronounced, and his will determined; even "evils", as it is in the plural number; not the evil of sin, or of fault; this comes not out of the mouth of God, but is forbidden and condemned by him; much less is he the author of it, or tempter to it; indeed it is not without his knowledge, nor in some sense without his will; not with his will of approbation, but by his permissive will, which he suffers to be, and overrules for good; but evils here design the judgments of God, or punishment inflicted on sinners, and chastisement on his own people; the evil of affliction, or adverse dispensations of providence, Isa 45:7; they are all by his appointment; he has said or determined what shall be the kind and nature of them; the measure, how far they shall go; and the duration, how long they shall last; and the end and use of them; see Job 2:10; and so all good comes from God, who is goodness itself; all created good, as every creature of God is good; every good thing in providence; all temporal good things; as to have a being; to be preserved in it; to have a habitation to dwell in; to have food and raiment, health and long life; these are all by the appointment of God, and according to the determination of his will: all spiritual good things are purposed, promised, and prepared by him in council and covenant; the great good of all, salvation by Christ; this is what God has appointed his son far, and his people to, and fixed the time of it, and all things relating to it; the effectual calling of the redeemed ones is according to his purpose and grace; the persons, thing itself, time, place, and means; also eternal glory and happiness, which is the kingdom prepared, the crown laid up, and inheritance reserved in heaven, according to the purpose of God; all good things, in time and eternity, are as God has pronounced them. ; and so all good comes from God, who is goodness itself; all created good, as every creature of God is good; every good thing in providence; all temporal good things; as to have a being; to be preserved in it; to have a habitation to dwell in; to have food and raiment, health and long life; these are all by the appointment of God, and according to the determination of his will: all spiritual good things are purposed, promised, and prepared by him in council and covenant; the great good of all, salvation by Christ; this is what God has appointed his son far, and his people to, and fixed the time of it, and all things relating to it; the effectual calling of the redeemed ones is according to his purpose and grace; the persons, thing itself, time, place, and means; also eternal glory and happiness, which is the kingdom prepared, the crown laid up, and inheritance reserved in heaven, according to the purpose of God; all good things, in time and eternity, are as God has pronounced them. Lamentations 3:39 lam 3:39 lam 3:39 lam 3:39Wherefore doth a living man complain?.... Or murmur, or fret and vex, or bemoan himself; all which the word (k) may signify; as the prophet had done in his own person; or as representing the church, Lam 3:1; and here checks himself for it; and especially since the mercies and compassions of God never fail, and are daily renewed; and the Lord himself is the portion of his people, Lam 3:23; and seeing he is good to them that seek him, and it is good to wait quietly for the salvation of God, and to bear the yoke patiently, Lam 3:25; and because of the unwillingness of God to afflict men, and his sympathy and compassion towards them under affliction, Lam 3:32; and especially since all is from the sovereignty of God, who does according to his will; and from whom all good and evil come, Lam 3:37; he is not to be complained of, or against, for anything he does; or to be murmured at; nor should men vex and fret themselves at their own adversity, or at the prosperity of others; or bemoan themselves, as if no case was like theirs, or so bad. It does not become "a man", a reasonable creature, a man grown up, to behave in this manner; as such should quit themselves like men, and conduct as such; a "man" that God is so mindful of, and cares for, and visits every moment, and follows with his goodness continually; a "man", sinful man, that has rendered himself unworthy of the least favour; and yet such is the lovingkindness, favour, and good will of God to man, that he has provided his own Son to be his Saviour; and therefore man, of all God's creatures, has no reason to complain of him; and is a "living" man too, in a natural sense; is upheld in life by the Lord, and has the common mercies of life; is in health, or however in the land of the living; out of hell, where he deserves to be; and therefore should praise, and not complain, Isa 38:19; especially if he is a living man in a spiritual sense; has a principle of spiritual life implanted in him; Christ lives in him, and his life is hid with him in God, and has a right and title to eternal life: a man for the punishment of his sins? the word "punishment" is not in the text; but, admitting the supplement, if a man is a wicked man (and so the Targum interprets it), and is punished for his sins, no injustice is done him; he has no reason to complain; and especially of his punishment in this world, which is greatly less than his sins deserve, Ezr 9:13; and if he is a good man, and is chastised for his sins, he ought not to complain "for the chastisement" of them; since it is the chastisement of a father, is in love, and for his good: but the words may be rendered literally, "a man for", or "of his sins" (l); and be considered as a distinct clause, and as an answer to the former, so Jarchi; if a man will complain, let him complain of his sins; of the corruptions of his heart; of the body of sin and death he carries about with him of his daily iniquities; let him mourn over them, and bemoan himself for them; and if he does this in an evangelic manner, he is happy; for he shall be comforted.
