Isaac obeyed the command of God, and he settled in Gerar. When he noticed that the inhabitants of the place began to have designs upon his wife, he followed the example of Abraham, and pretended she was his sister. The report of Rebekah's beauty reached the king himself, but he was mindful of the great danger to which he had once exposed himself on a similar occasion, and he left Isaac and his wife unmolested.
After they had been in Gerar for three months, Abimelech noticed that the manner of Isaac, who lived in the outer court of the royal palace, was that of a husband toward Rebekah. He called him to account, saying, "It might have happened to the king himself to take the woman thou didst call thy sister." Indeed, Isaac lay under the suspicion of having illicit intercourse with Rebekah, for at first the people of the place would not believe that she was his wife.
When Isaac persisted in his statement, Abimelech sent his grandees for them, ordered them to be arrayed in royal vestments, and had it proclaimed before them, as they rode through the city: "These two are man and wife. He that toucheth this man or his wife shall surely be put to death."
