Isaiah 63:16

He reminded God that He was Israel’s true Father. Abraham and Israel (Jacob) may have forgotten their children and may have been incapable of helping them, but the Lord had not forgotten and could help. A second basis for appealing for help was that Yahweh had been Israel’s Redeemer in the past as well as its Father (cf. Isaiah 63:12; Isaiah 63:14). Fathers characteristically feel affection and compassion for their children (Isaiah 63:15), and redeemers (kinsman-redeemers) normally demonstrate zeal and perform mighty deeds for their relatives (Isaiah 63:15).
