Albert Barnes Commentary Job 13:16

"This also shall be my salvation, That a godless man shall not come before him." — Job 13:16 (ASV)

He also shall be my salvation – See the notes at Isaiah 12:2. Literally, “He is to me for salvation,” that is, “I put my trust in Him, and He will save me. The opportunity of appearing before God, and of maintaining my cause in His presence, will result in my deliverance from the charges which are alleged against me. I will be able there to show that I am not a hypocrite, and God will become my defender.”

For an hypocrite shall not come before Him – This seems to be a proverb, or a statement of a general and indisputable principle. Job admitted this to be true. Yet he expected to be able to vindicate himself before God, and this would prove that he was not a hypocrite – on the general principle that a man who was permitted to stand before God and to obtain His favor, could not be an unrighteous man. To God he looked with confidence; and God, he had no doubt, would be His defender. This fact would prove that he could not be a hypocrite, as his friends maintained.
