Then Job arose, and {a} rent his mantle, and shaved his head, and fell down upon the ground, and worshipped,

(a) Which came not from impatience, but declares that the children of God are not insensible like blocks, but that in their patience they feel affliction and grief of mind: yet they do not rebel against God as the wicked do.

Wesley's Notes

1:20 Shaved - Caused his hair to be shaved or cut off, which was then an usual ceremony in mourning. Worshipped - Instead of cursing God, which Satan said he would do, he adored him, and gave him the glory of his sovereignty, of his justice, and of his goodness also, in this most severe dispensation.

King James Translators' Notes

mantle: or, robe

Jamieson-Fausset-Brown Bible Commentary

20. Job arose-not necessarily from sitting. Inward excitement is implied, and the beginning to do anything. He had heard the other messages calmly, but on hearing of the death of his children, then he arose; or, as Eichorn translates, he started up (2Sa 13:31). The rending of the mantle was the conventional mark of deep grief (Ge 37:34). Orientals wear a tunic or shirt, and loose pantaloons; and over these a flowing mantle (especially great persons and women). Shaving the head was also usual in grief (Jer 41:5; Mic 1:16).

Matthew Henry's Concise Commentary

1:20-22 Job humbled himself under the hand of God. He reasons from the common state of human life, which he describes. We brought nothing of this world's goods into the world, but have them from others; and it is certain we can carry nothing out, but must leave them to others. Job, under all his losses, is but reduced to his first state. He is but where he must have been at last, and is only unclothed, or unloaded rather, a little sooner than he expected. If we put off our clothes before we go to bed, it is some inconvenience, but it may be the better borne when it is near bed-time. The same who gave hath taken away. See how Job looks above instruments, and keeps his eye upon the First Cause. Afflictions must not divert us from, but quicken us to religion. If in all our troubles we look to the Lord, he will support us. The Lord is righteous. All we have is from his gift; we have forfeited it by sin, and ought not to complain if he takes any part from us. Discontent and impatience charge God with folly. Against these Job carefully watched; and so must we, acknowledging that as God has done right, but we have done wickedly, so God has done wisely, but we have done very foolishly. And may the malice and power of Satan render that Saviour more precious to our souls, who came to destroy the works of the devil; who, for our salvation, suffered from that enemy far more than Job suffered, or we can think.
