17O God, thou hast taught me from my youth: and hitherto have I declared thy wondrous works. 18Now also when I am old and grayheaded, O God, forsake me not; until I have shewed thy strength unto this generation, and thy power to every one that is to come. 19Thy righteousness also, O God, is very high, who hast done great things: O God, who is like unto thee! 20Thou, which hast shewed me great and sore troubles, shalt quicken me again, and shalt bring me up again from the depths of the earth.21Thou shalt increase my greatness, and comfort me on every side. 22I will also praise thee with the psaltery, even thy truth, O my God: unto thee will I sing with the harp, O thou Holy One of Israel. 23My lips shall greatly rejoice when I sing unto thee; and my soul, which thou hast redeemed.
