Isaac repeats the ruse his father used in Egypt and Gerar many years earlier. Abraham told another Abimelech (likely the father or grandfather of this Philistine king) that Sarah was his sister to avoid being killed. Isaac tries the same trick for the same reason but is soon found out. Many rulers in that day would have killed or severely punished a man for telling such tales and jeopardizing their reign. Somehow, however, Abraham and Isaac not only survive, but they grow rich from the experiences.
