Do more than purify me, do more than cleanse me; by an act of creative power make in me a new clean heart. Compare the Christian doctrine of the "new birth" and "new life." And renew a right spirit within me.
"Heart" and "spirit" are used interchangeably for the inward essence of man; but, as Professor Cheyne observes, "Heart emphasizes the individual side of a man's life; spirit, its Divine, or at least preternatural side." David, in asking both for a new heart and a new spirit, requests the renovation of his entire mental and moral nature, which he recognizes as corrupt and depraved.
[Pulpit Commentary]
Psalm 51:10 ... Create in me a clean heart, O God; and renew a right spirit within me. ❤
