KJV: 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.
NASB: And even when I am old and gray, O God, do not forsake me, Until I declare Your strength to this generation, Your power to all who are to come.
KJV: The days of our years are threescore years and ten; and if by reason of strengththey be fourscore years, yet is their strength labour and sorrow; for it is soon cut off, and we fly away.
NASB: As for the days of our life, they contain seventy years, Or if due to strength, eighty years, Yet their pride is but labor and sorrow; For soon it is gone and we fly away.
