Isaiah 19
18 Ref In that day there shall be five cities in the land of Egypt that speak the language of Canaan, and swear to Yahweh of hosts; one shall be called The city of destruction.
19 Ref In that day shall there be an altar to Yahweh in the midst of the land of Egypt, and a pillar at the border of it to Yahweh.
20 Ref It shall be for a sign and for a witness to Yahweh of Hosts in the land of Egypt; for they shall cry to Yahweh because of oppressors, and he will send them a savior, and a defender, and he will deliver them.
21 Ref Yahweh shall be known to Egypt, and the Egyptians shall know Yahweh in that day; yes, they shall worship with sacrifice and offering, and shall vow a vow to Yahweh, and shall perform it.
