Genesis 12:18

And Pharaoh called Abram, and said, What is this that thou hast done unto me? why didst thou not tell me that she was thy wife?

What is this that thou hast done unto me? - (cf. Genesis 20:5.) The divine judgment which was inflicted on his house had probably led him to make inquiry; and having learned, perhaps from Sarai herself, the real truth, he was justly indignant. Here is a most humiliating rebuke, and Abram deserved it. Had not God interfered, he might have been tempted to stay in Egypt, and forget the promise (Psalms 105:13; Psalms 105:15). Often still does God rebuke His people, and remind them, through enemies, that this world is not their rest.
