Lot’s daughters, I struggle with this sleeping with their father in order to get pregnated… anyhow Moab was born to one and Ben-ammi to the other and so the Moabites and Ammonite tribes were born.
It’s amazing how God tells Abraham to listen to Sarah in regards to her slave Hagar and Abraham’s son Ishmael and then God promises are again spoken that his offspring will make a nation from him because he is his son. Here in Genesis 25:16 we read about the 12 leaders from Ishmaels 12 sons. Nebaioth, Kedar, Adbeel, Mibsam, Mishma, Dumah, Massa, Hadad, Tema, Jetur, Naphish, and Kedemah. This was promised in Genesis 17; 20 Will multiply him greatly. He will father 12 tribal leaders and will make him into a great nation.
I can’t imagine having to take one of my kids for a sacrifice. Abraham’s fear of the Lord and faithfulness was vastly great. But then you hear God talking to Abraham through this trial which must have been very calming to him. I note that Abraham seemed to have had that assurance that God would provide a lamb for the sacrifice because he told his young men “we’ll come back to you” and then he told Isaac too that God will provide a lamb! As scripture says God will provide all our needs according to His riches in Glory in Christ Jesus. Philippians 4:19
The birth of Isaac and Sarah’s words were “God has made me laugh”
Sarah died at the age of 127 years and was buried in a cave of a field at Machpelah near Mamre (Hebron) The field with its cave passed from the Hittite’s to Abraham as a burial place.
