Yitzhkak (Isaac) seems to have repeated a number of events from Abraham’s life: a famine and claiming his wife was his sister. Yitzkhak also seems to have been obsessed with digging wells, but what should get our attention are messianic symbols of three days of live and death in the ground.
Abraham seals a contract with King Abimelech for a well and seals it with a seven-fold oath in the form of seven ewes.
In part three of a study on Genesis 21, we read about the confrontation between the ruler Abimelech and Abraham. Meanwhile, Ishmael grows up and becomes a problem in Abraham’s household, so Abraham sends him and his mother away.
