11 “For Your Name's sake, O Lord, You will be favourable to my sin; for it is manifold”. You have not only forgiven my sins, which I committed before I believed; but also to my sin, which is manifold, since even in the way there is no lack of stumbling, You will be made favourable by the sacrifice of a troubled spirit.
