|Matthew Henry's Concise Commentary|
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.
Verse 24. - In that day shall Israel be the third; rather, a third. Not third in rank, for ver. 25 shows that she would retain a pre-eminence, but the common intermediary, brining the other two together. A blessing in the midst of the land; rather, in the midst of the earth. Judaean monotheism, upheld by God's people in Palestine, Egypt, and Mesopotamia, would be a blessing, not only to those three countries, but to the world at large. So, and still more, would Christianity.
Gill's Exposition of the Entire Bible
In that day shall Israel be the third with Egypt and with Assyria,.... There shall be a triple alliance between them; Jew and Gentile shall be made one, the middle wall of partition being broken down; yea, Israel, or the Jews, shall be the third, or the Mediator between them both, or the means of uniting the Gentiles together, since the Gospel of peace was to go out from them, as it did. Perhaps there may be an allusion to the situation of the land of Israel between Egypt and Assyria:
even a blessing in the midst of the land; or of the earth, the whole world, being the means of conveying the blessings of grace to the several nations of the world; the Messiah, in whom all nations are blessed, descending from them, and the Gospel being sent out from them unto all nations, which publishes the blessings of grace by Christ, and is the means both of the knowledge, application, and possession of them.
Jamieson-Fausset-Brown Bible Commentary
24. third—The three shall be joined as one nation.
blessing—the source of blessings to other nations, and the object of their benedictions.
in the midst of the land—rather, "earth" (Mic 5:7). Judah is designed to be the grand center of the whole earth (Jer 3:17).
