Psalms 71:18-19

Now 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. {when...: Heb. unto old age and gray hairs} {thy strength: Heb. thine arm} Thy righteousness also, O God, {is} very high, who hast done great things: O God, who {is} like unto thee!
