Genesis 12:17 - Wesley's Explanatory Notes

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.
