Isaiah 19:20-22

20Those two things will be signs to tell everyone in Egypt about the Lord Almighty. Because of those signs, the Egyptians will remember that the Lord is powerful. When their enemies are cruel to them, they will call out to the Lord for help. Then he will send a strong saviour to rescue them.

21The Lord will cause the Egyptians to know him. They will agree to serve him. They will worship the Lord with sacrifices and offerings. They will make promises to the Lord, and they will do what they have promised to do.

22The Lord himself will punish the Egyptians. But after that, they will turn to the Lord. He will answer their prayers, and he will make them well again.
