Genesis 21 - Introduction

1 7. The Birth of Isaac. (J and P.)

8 21. The Expulsion of Hagar and Ishmael. (E.)

22 34. The Covenant between Abraham and Abimelech at Beer-sheba. (E and J.)

The greater part of this chapter is from E. But Genesis 21:1 a, Genesis 21:2 a, and 7 are probably from J; and Genesis 21:1 b, Genesis 21:2 from P; Genesis 21:6 is E.
