Abimelech, the King of Garar, Said, She Is My Sister

Abraham said to sarah, his wife, she is my sister. And abimelech, the king of garar, sent and took sarah. But in a dream by night god came to abimeleCh saying he was going to slay an innocent people. Now then, restore the man's wife, for he is a prophet, and he will pray for you and you shall live. If you do not restore her, know that you shall surely die, you and all that are yours. Abraham: She indeed is my sister,  the daughter of my father, but not the daughter of my mother. The men were very much afraid.
