Genesis 26:9-11

Young's Literal Translation

⁹ And Abimelech calleth for Isaac, and saith, `Lo, she [is] surely thy wife; and how hast thou said, She [is] my sister?' and Isaac saith unto him, `Because I said, Lest I die for her.'

¹⁰ And Abimelech saith, `What [is] this thou hast done to us? as a little thing one of the people had lain with thy wife, and thou hadst brought upon us guilt;'

¹¹ and Abimelech commandeth all the people, saying, `He who cometh against this man or against his wife, dying doth die.'
