Matthew Henry 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)

It is folly to indulge sin, and excuse it. He who covers his sins, shall not have any true peace. He who humbly confesses his sins, with true repentance and faith, shall find mercy from God. The Son of God is our great atonement. Under a deep sense of our guilt and danger, we may claim salvation from that mercy which reigns through righteousness unto eternal life, by Jesus Christ our Lord.
