A land of darkness, as darkness itself; and of the shadow of death, without any {u} order, and where the light is as darkness.

(u) No distinction between light and darkness but where there is very darkness itself.

Jamieson-Fausset-Brown Bible Commentary

22. The ideas of order and light, disorder and darkness, harmonize (Ge 1:2). Three Hebrew words are used for darkness; in Job 10:21 (1) the common word "darkness"; here (2) "a land of gloom" (from a Hebrew root, "to cover up"); (3) as "thick darkness" or blackness (from a root, expressing sunset). "Where the light thereof is like blackness." Its only sunshine is thick darkness. A bold figure of poetry. Job in a better frame has brighter thoughts of the unseen world. But his views at best wanted the definite clearness of the Christian's. Compare with his words here Re 21:23; 22:5; 2Ti 1:10.

Matthew Henry's Concise Commentary

10:14-22 Job did not deny that as a sinner he deserved his sufferings; but he thought that justice was executed upon him with peculiar rigour. His gloom, unbelief, and hard thoughts of God, were as much to be ascribed to Satan's inward temptations, and his anguish of soul, under the sense of God's displeasure, as to his outward trials, and remaining depravity. Our Creator, become in Christ our Redeemer also, will not destroy the work of his hands in any humble believer; but will renew him unto holiness, that he may enjoy eternal life. If anguish on earth renders the grave a desirable refuge, what will be their condition who are condemned to the blackness of darkness for ever? Let every sinner seek deliverance from that dreadful state, and every believer be thankful to Jesus, who delivereth from the wrath to come.
