Albert Barnes Commentary Proverbs 28:13

"He that covereth his transgressions shall not prosper: But whoso confesseth and forsaketh them shall obtain mercy." — Proverbs 28:13 (ASV)

The conditions of freedom are confession and amendment, confession to God of sins against Him, to men of sins against them. The teaching of ethical wisdom on this point is identical with that of psalmist, prophet, apostles, and our Lord Himself.
