Abraham: Teaching that Those of Egypt are heirs by Faith

In Isaiah 19:1-20:6, we read where as God's purging Egypt through judgment upon them, that those He has chosen by Faith (Strangers to Covenant) become children and believers, bringing offerings and prayers to The House of God. Ishmael and the descendants of Ham (Noah's son) receive of those great promises of God to the seed of Abraham Father of many nations. He told Hagar in Genesis, He world make that child a nation.
