Isaiah 19:19-21

Revised Standard Version

¹⁹ In that day there will be an altar to the Lord in the midst of the land of Egypt, and a pillar to the Lord at its border. ²⁰ It will be a sign and a witness to the Lord of hosts in the land of Egypt; when they cry to the Lord because of oppressors he will send them a savior, and will defend and deliver them. ²¹ And the Lord will make himself known to the Egyptians; and the Egyptians will know the Lord in that day and worship with sacrifice and burnt offering, and they will make vows to the Lord and perform them.
