If I sin, then thou markest me, and thou wilt not acquit me from mine iniquity.

Wesley's Notes

10:14 Markest - If I am a wicked man, I cannot hide it from thee; and thou wilt punish me for it.

Jamieson-Fausset-Brown Bible Commentary

14, 15. Job is perplexed because God "marks" every sin of his with such ceaseless rigor. Whether "wicked" (godless and a hypocrite) or "righteous" (comparatively sincere), God condemns and punishes alike.

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.
