21And 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. 22And the LORD will smite Egypt, smiting and healing, and they will return to the LORD, and he will heed their supplications and heal them.
24In that day Israel will be the third with Egypt and Assyria, a blessing in the midst of the earth, 25whom the LORD of hosts has blessed, saying, "Blessed be Egypt my people, and Assyria the work of my hands, and Israel my heritage."
Isaiah 19:21-25 (RSV)
