Isaiah 19:19-21

New Revised Standard Version, Anglicised

¹⁹ On that day there will be an altar to the Lord in the centre 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 saviour, and will defend and deliver them. ²¹ The Lord will make himself known to the Egyptians; and the Egyptians will know the Lord on that day, and will worship with sacrifice and burnt-offering, and they will make vows to the Lord and perform them.
