Isaiah 19:19-21

Darby Translation

¹⁹ 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:

²⁰ and it shall be for a sign and for a witness to Jehovah of hosts in the land of Egypt; for they shall cry unto Jehovah because of the oppressors, and he will send them a saviour and defender, who shall deliver them.

²¹ And Jehovah shall be known to the Egyptians, and the Egyptians shall know Jehovah in that day, and shall serve with sacrifice and oblation; and they shall vow a vow unto Jehovah, and perform it.
