To deliver their soul from death, and to keep them alive in famine.
All Commentaries on Psalms 33:19 Go To Psalms 33
Augustine of Hippo
AD 430
19. "To denver their souls from death, and to keep them alive in famine" (ver. 19). To give them the nourishment of the Word, and of Everlasting Truth, which they lost while presuming on their own strength, and therefore have not even their own strength, from lack of righteousness.
