INTRODUCTION TO GENESIS 21 This chapter gives an account of the conception, birth, circumcision, and weaning of Isaac, Gen 21:1; of the mocking of Ishmael, and of the casting out of him and his mother from Abraham's house, at the request of Sarah, which, though grievous to Abraham, he complied with at the direction of God, Gen 21:9; of the provision Abraham made for their departure, and of the supply they met with in the wilderness from God, where Ishmael was brought up, and where he married, Gen 21:14; and of a covenant between Abraham and Abimelech, king of Gerar, Gen 21:22; and of Abraham's planting a grove, and calling on the name of the Lord, Gen 21:33; and the chapter is closed with this observation, that Abraham sojourned in the land of the Philistines many days, Gen 21:34.
