The Lord, who redeemed Abraham; rather, who delivered Abraham, as the verb used is often rendered (see Job 33:28; Psalms 51:18; Psalms 69:18; Psalms 78:42, etc.). God's directions to Abraham to remove from a land of idolaters (Joshua 24:2, Joshua 24:3; Acts 7:2, Acts 7:3) were practically a "deliverance."
The work thus commenced could not be suffered to remain incomplete. Israel—the true Israel—would not be ashamed, or wax pale through fear any more; they would be God's children, his true worshippers, and would have no need to experience either fear or shame.
