The Wife of Abraham Was Sarahi, Right?

The wife of abraham was sarahi, for those of you that are not biblical leolined. For this new alliance, i'm almost certain that god directs abraham to lay with hagar to produce the oftenin. He introduces sarah as his sister for pharaoh to lay with as a concubine, or whatever. And God kind of gets angry, and the pharaoh's god, just go away, take your sister, and here, take all, take some flocks of goats and sheep."
