[Then] will I teach transgressors thy ways
David was a prophet as well as a king; see ( Acts 2:30 ) ; and taught men the fear of the Lord, ( Psalms 34:11 ) , and instructed them in his ways, as he here promises he would; by which are meant, either the ways which God prescribes and directs men to walk in, as the paths of faith, holiness, and truth, and the ways of his commandments; or which he himself has walked in; meaning not the ways of his providence, which are sometimes past finding out; but the ways of his grace, the steps and methods he has taken in the salvation of men, by forming the scheme of it, by choosing unto it, by making a covenant with his Son, and appointing him to effect it; and particularly his ways and methods in receiving and pardoning backsliders, when returned by repentance to him; and who may be meant by "transgressors" here: and then the sense is, that David, upon his being received and pardoned, would teach others like himself how graciously God had dealt with him; how plenteous he is in mercy; how ready to forgive, and how faithful to his promises; and so encourage them to go to him, and acknowledge their transgressions, and seek pardoning grace at his hands, who does abundantly pardon, and whose ways are not as theirs; see ( Isaiah 55:7-9 ) ;
and sinners shall be converted unto thee:
or "that sinners may be converted unto thee" F16; this being the end of teaching by the word, and the means of the conversion of profane and unregenerate sinners, through the power of divine grace; though rather this seems to be understood of the conversion of God's own people after backslidings, and not of first conversion; see ( Luke 22:32 ) ( James 5:19 James 5:20 ) .
