17O God! thou hast taught me from my youth, And thus far have I declared thy wondrous deeds;
18And now, when I am old and gray-headed, O God! forsake me not, Until I make known thine arm to the next generation,-Thy mighty power to all that are to come!
19For thy goodness, O God! reacheth to the heavens; Wonderful things doest thou! O God! who is like unto thee?
