Genesis 20:1-3

Abraham traveled from there south to the Negev and settled down between Kadesh and Shur. While he was camping in Gerar, Abraham said of his wife Sarah, “She’s my sister.” So Abimelech, king of Gerar, sent for Sarah and took her. But God came to Abimelech in a dream that night and told him, “You’re as good as dead—that woman you took, she’s a married woman.”
