The mouth of the righteous speaks wisdom, and his tongue talks of justice.
All Commentaries on Psalms 37:30 Go To Psalms 37
Augustine of Hippo
AD 430
11. "The mouth of the righteous speaketh wisdom" (ver. 30). See here is that "bread." Observe with what satisfaction this righteous man feedeth upon it; how he turns wisdom over and over in his mouth. "And his tongue talketh of judgment."
