This chapter gives an account of the conception, birth, circumcision,
and weaning of Isaac, \\#Ge 21:1-8\\; 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, \\#Ge 21:9-13\\; 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,
\\#Ge 21:14-21\\; and of a covenant between Abraham and Abimelech, king
of Gerar, \\#Ge 21:22-32\\; and of Abraham's planting a grove, and
calling on the name of the Lord, \\#Ge 21:33\\; and the chapter is
closed with this observation, that Abraham sojourned in the land of the
Philistines many days, \\#Ge 21:34\\.
