After Abraham’s momentary lapse of faith (and the rescue of Sarah – again [Genesis chapter 20]), God fulfills his promise to Abraham, and Isaac is born. There is much celebrating until Ishmael is seen taunting Isaac and Sarah demands that he and his mother Hagar be sent away. Abraham obeys God and He reassures him that He will bless his son. Abraham then settles in the land of Gerar of the Philistines and establishes public worship of the one true God.
