Some explain the verb yt'vnn, itaunen, by giving it the sense of lying, "Why should man lie?" others, "Why should man murmur?" But I see not what sense there can be in rendering it lying or murmuring. Others translate thus, "Why should man harden himself?" but it is a mere conjecture. Now, this verb sometimes means to weary one's self, in Hithpael. So in the eleventh chapter of Numbers, "The people murmured," as some render the words; but I think differently; nor is there a doubt but that Moses meant that the people were wearied, so that they in a manner pined away; and this meaning is the most suitable here. For the Prophet had before rebuked those who imagined that God, having relinquished the care of the world, led an inactive and easy life in heaven; but now, in order to rouse the minds of all, he points out the remedy for this madness, even that men should not willingly weary themselves in their sins, but acknowledge that their wickedness is shewn to them whenever any adversity comes upon them. And surely men would not be so infatuated as to exclude God from the government of the world, were they to know themselves and seriously to call to mind their own deeds and words; for God would soon exhibit to them sure and notorious examples of his judgment. Whence then comes it, that we are so dull and stupid in considering the works of God? nay, that we think that God is like a spectre or an idol? even because we rot in our sins and contract a voluntary dullness; for we champ the bit, according to the old proverb. We now, then, perceive why the Prophet joins this sentence, Why does a living man weary himself? [1] and a man in his sins? for as long as men thus remain in their own dregs, they will never acknowledge God as the judge of the world, and thus they always go astray through their own perverse imaginations. If, then, we wish to dissipate all the mists which prevent us from seeing God's providence, (that is, by the eyes of faith,) let every one be his own witness and the judge of his own life, and carefully examine himself; it will then immediately occur to us, that God is not without reason angry with us, and that we are afflicted with so many adversities, because our sins will come forth before us. We here see the cause of that madness which makes men to exclude God's providence from human affairs, even because they look not on themselves, but torment themselves without any benefit and become wearied in their sins, and do not raise up their eyes to God. The rest, connected with our subject, I must defer till to-morrow.

Footnotes

1 - "Murmur" is the Sept. and the Vulg. The word only occurs here and in Numbers 11:1; and "complain" is the most suitable rendering in both places, -- 39. Why complain should man, Any man alive, for his sin? That is, on account of suffering for his sin. Thus God is justified in ordaining or commanding evil as well as good, that is, the evil of punishment. -- Ed.

So long as God spares a man's life, why does he complain? The chastisement is really for his good; only let him use it aright, and he will be thankful for it in the end.
A man for the punishment of his sins - Translate: Let "each man sigh for," i. e. because of, "his sins." Instead of complaining because God sends him sorrow, let him rather mourn over the sins which have made punishment necessary. The sense of the King James Version is, Why does a man complain "for his sins?" i. e. for the necessary results of them in chastisement.

Wherefore doth a living man complain - He who has his life still lent to him has small cause of complaint. How great soever his affliction may be, he is still alive; therefore, he may seek and find mercy unto eternal life. Of this, death would deprive him; therefore let not a living man complain.

Why doth a living (t) man complain, a man for the punishment of his sins?
(t) When God afflicts him.

Wherefore 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, Lamentations 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, Lamentations 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, Lamentations 3:25; and because of the unwillingness of God to afflict men, and his sympathy and compassion towards them under affliction, Lamentations 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, Lamentations 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, Isaiah 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, Ezra 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.

living--and so having a time yet given him by God for repentance. If sin were punished as it deserves, life itself would be forfeited by the sinner. "Complaining" (murmuring) ill becomes him who enjoys such a favor as life (Proverbs 19:3).
for the punishment of his sins--Instead of blaming God for his sufferings, he ought to recognize in them God's righteousness and the just rewards of his own sin.

Wherefore - The Jews, check themselves in their complaints from the consideration, that nothing had befallen them, but what was the just reward of their sins.
