Isaiah 19:18-22

In that day there shall be five cities in the land of Egypt that speak the language of Canaan, and swear to Jehovah of hosts; one shall be called The city of destruction. In that day shall there be an altar to Jehovah in the midst of the land of Egypt, and a pillar at the border thereof to Jehovah. And it shall be for a sign and for a witness unto Jehovah of hosts in the land of Egypt; for they shall cry unto Jehovah because of oppressors, and he will send them a saviour, and a defender, and he will deliver them. And Jehovah shall be known to Egypt, and the Egyptians shall know Jehovah in that day; yea, they shall worship with sacrifice and oblation, and shall vow a vow unto Jehovah, and shall perform it. 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.
