Isaiah 19:19-21 King James Version (KJV)
19 In that day shall there be an altar to the Lord in the midst of the land of Egypt, and a pillar at the border thereof to the Lord.
20 And it shall be for a sign and for a witness unto the Lord of hosts in the land of Egypt: for they shall cry unto the Lord because of the oppressors, and he shall send them a saviour, and a great one, and he shall deliver them.
21 And the Lord shall be known to Egypt, and the Egyptians shall know the Lord in that day, and shall do sacrifice and oblation; yea, they shall vow a vow unto the Lord, and perform it.
Isaiah 19:19-21 New International Version (NIV)
19 In that day there will be an altar to the Lord in the heart of Egypt, and a monument to the Lord at its border. 20 It will be a sign and witness to the Lord Almighty in the land of Egypt. When they cry out to the Lord because of their oppressors, he will send them a savior and defender, and he will rescue them. 21 So the Lord will make himself known to the Egyptians, and in that day they will acknowledge the Lord. They will worship with sacrifices and grain offerings; they will make vows to the Lord and keep them.
