20It 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. 21So 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.
22The LORD will strike Egypt with a plague; he will strike them and heal them. They will turn to the LORD, and he will respond to their pleas and heal them.
