18 In that day five cities in Egypt will speak the language of Canaan and swear allegiance to the Lord Almighty. One of them will be called the City of the Sun.[1] 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. 22 The 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.
18 In that day shall five cities in the land of Egypt speak the language
18 In that day there will be five cities in the land of Egypt that speak the language of Canaan and swear allegiance to the Lord of hosts. One of these will be called the City of Destruction.
18 On that Day, more than one city in Egypt will learn to speak the language of faith and promise to follow God-of-the-Angel-Armies. One of these cities will be honored with the title "City of the Sun." 19 On that Day, there will be a place of worship to God in the center of Egypt and a monument to God at its border. 20 It will show how the God-of-the-Angel-Armies has helped the Egyptians. When they cry out in prayer to God because of oppressors, he'll send them help, a savior who will keep them safe and take care of them. 21 God will openly show himself to the Egyptians and they'll get to know him on that Day. They'll worship him seriously with sacrifices and burnt offerings. They'll make vows and keep them. 22 God will wound Egypt, first hit and then heal. Egypt will come back to God, and God will listen to their prayers and heal them, heal them from head to toe.
18 In that day five cities in the land of Egypt will speak the language of Canaan and swear by the Lord of hosts; one will be called the City of Destruction. 19 In that day there will be an altar to the Lord in the midst of the land of Egypt, and a pillar to the Lord at its border. 20 And it will be for a sign and for a witness to the Lord of hosts in the land of Egypt; for they will cry to the Lord because of the oppressors, and He will send them a Savior and a Mighty One, and He will deliver them. 21 Then the Lord will be known to Egypt, and the Egyptians will know the Lord in that day, and will make sacrifice and offering; yes, they will make a vow to the Lord and perform it. 22 And the Lord will strike Egypt, He will strike and heal it; they will return to the Lord, and He will be entreated by them and heal them.
18 In that day five of Egypt's cities will follow the Lord of Heaven's Armies. They will even begin to speak Hebrew, the language of Canaan. One of these cities will be Heliopolis, the City of the Sun. 19 In that day there will be an altar to the Lord in the heart of Egypt, and there will be a monument to the Lord at its border. 20 It will be a sign and a witness that the Lord of Heaven's Armies is worshiped in the land of Egypt. When the people cry to the Lord for help against those who oppress them, he will send them a savior who will rescue them. 21 The Lord will make himself known to the Egyptians. Yes, they will know the Lord and will give their sacrifices and offerings to him. They will make a vow to the Lord and will keep it. 22 The Lord will strike Egypt, and then he will bring healing. For the Egyptians will turn to the Lord, and he will listen to their pleas and heal them.
Matthew Henry's Commentary on Isaiah 19:18-22
Commentary on Isaiah 19:18-25
(Read Isaiah 19:18-25)
The words, "In that day," do not always refer to the passage just before. At a time which was to come, the Egyptians shall speak the holy language, the Scripture language; not only understand it, but use it. Converting grace, by changing the heart, changes the language; for out of the abundance of the heart the mouth speaks. So many Jews shall come to Egypt, that they shall soon fill five cities. Where the sun was worshipped, a place infamous for idolatry, even there shall be a wonderful reformation. Christ, the great Altar, who sanctifies every gift, shall be owned, and the gospel sacrifices of prayer and praise shall be offered up. Let the broken-hearted and afflicted, whom the Lord has wounded, and thus taught to return to, and call upon him, take courage; for He will heal their souls, and turn their sorrowing supplications into joyful praises. The Gentile nations shall not only unite with each other in the gospel fold under Christ, the great Shepherd, but they shall all be united with the Jews. They shall be owned together by him; they shall all share in one and the same blessing. Meeting at the same throne of grace, and serving with each other in the same business of religion, should end all disputes, and unite the hearts of believers to each other in holy love.
