“The princes also of Pharaoh saw her, and commended her before Pharaoh: and the woman was taken into Pharaoh's house.”
King James Version (KJV)
12:13 Say thou art my sister - The grace Abram was most eminent for was faith, and yet he thus fell through unbelief and distrust of the divine Providence, even after God had appeared to him twice. Alas, What will become of the willows, when the cedars are thus shaken
12:17 And the Lord plagued Pharaoh and his house - Probably, those princes especially that had commended Sarai to Pharaoh. We are not told, particularly, what these plagues were; but, doubtless, there was something in the plagues themselves, or some explication added to them, sufficient to convince them that it was for Sarai's sake they were thus plagued.
