Isaiah 19:11, 22

The princes of Zoan are utterly foolish; the counsel of the wisest counsellors of Pharaoh is become brutish: how say ye unto Pharaoh, I am the son of the wise, the son of ancient kings?

And Jehovah will smite Egypt, smiting and healing; and they shall return unto Jehovah, and he will be entreated of them, and will heal them.
