i. Ps 19:11-12. Moreover by them is thy servant warned: and in keeping of them there is great reward. Who can understand his errors? cleanse thou me from secret faults. Rom 3:20. Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin. Rom 7:7. What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
