Be of good courage, and he shall strengthen your heart, all you that hope in the LORD.
All Commentaries on Psalms 31:24 Go To Psalms 31
Augustine of Hippo
AD 430
25. "Quit you like men, and let your heart be strengthened" (ver. 24): working good without fainting, that ye may reap in due season. "All ye who trust in the Lord:" that is, ye who duly fear and worship Him, trust ye in the Lord.
