Cast me not off in the time of old age; forsake me not when my strength faileth.
Cast me not off in the time of old age - since thou hast been my support, and therefore "my trust from my youth" (Psalms 71:5), I confidently ask thee not to cast me off in my old age. My very weakness, through years, is a strong plea with thee for vouchsafing thy strength. God answers this prayer of the individual believer, of the Church, and of the literal Israel (primarily meant there) in Isaiah 46:3-4. 'The remnant of Israel' in the last days (the nation's old age) shall be 'delivered' by the God.
