Psalms 71:2

"In Thine own righteousness deliver me, and save me" (ver. 2). Not in mine own, but in Thine own: for if in mine own, I shall be one of those whereof he saith, "Being ignorant of God's righteousness, and their own righteousness willing to establish, to the righteousness of God they were not made subject." Therefore, "in Thine own righteousness," not in mine. For mine is what? Iniquity hath gone before. And when I shall be righteous, Thine own righteousness it will be: for by righteousness given to me by Thee I shall be righteous; and it shall be so mine, as that it be Thine, that is, given to me by Thee. For I believe on Him that justifieth an ungodly man, so that my faith is counted for righteousness. Even so then the righteousness shall be mine, not however as though mine own, not as though by mine own self given to myself: as they thought who through the letter made their boast, and rejected grace. ...It is a small thing then that thou acknowledge the good thing which is in thee to be from God, unless also on that account thou exalt not thyself above him that hath not yet, who perchance when he shall have received, will outstrip thee. For when Saul was a stoner of Stephen, how many were the Christians of whom he was persecutor! Nevertheless, when he was converted, all that had gone before he surpassed. Therefore say thou to God that which thou hearest in the Psalm, "In Thee I have hoped, O Lord, I shall not be confounded for everlasting: in Thine own righteousness," not in mine, "deliver me, and save me." "Incline unto me Thine ear." This also is a confession of humility. He that saith, "Incline unto me," is confessing that he is lying like a sick man laid at the feet of the Physician standing. Lastly, observe that it is a sick man that is speaking: "Incline unto me Thine ear, and save me."
