Charles Ellicott Commentary Job 29:14

"I put on righteousness, and it clothed me: My justice was as a robe and a diadem." — Job 29:14 (ASV)

I put on righteousness. — Compare to Isaiah 61:10; Isaiah 28:5; Isaiah 62:3; 2 Timothy 4:8; James 1:12; 1 Peter 5:4; 1 Thessalonians 2:19. His judgment, the result of his personal righteousness, was as a robe of honour and a crown of glory to him.

It clothed me. — Literally, it clothed itself with me. First, righteousness is the garment, and then he is the garment to righteousness. (Compare the expressions Put ye on the Lord Jesus Christ,Romans 13:14, and 2 Corinthians 5:2–4, and the Hebrew of Psalms 143:9, where I flee unto thee to hide me is, I have covered myself with thee, or, have hidden me with thee.) This is the Gospel truth of the interchange of sin and righteousness between Christ and the believer. He bears our sins; we are clothed with the robe of His righteousness.
