Whom the LORD of hosts shall bless, saying, Blessed be Egypt my people, and Assyria the work of my hands, and Israel mine inheritance.

Wesley's Notes

19:25 Whom - That is, which people, Israel, Egypt, and Assyria; of whom he speaks as of one people, because they are all united into one church. My people - This title, and those which follow, that were peculiar to the people of Israel, shall now be given to these and all other nations.

Jamieson-Fausset-Brown Bible Commentary

25. Whom-rather, "Which," namely, "the land," or "earth," that is, the people of it [Maurer].

my people-the peculiar designation of Israel, the elect people, here applied to Egypt to express its entire admission to religious privileges (Ro 9:24-26; 1Pe 2:9, 10).

work of my hands-spiritually (Ho 2:23; Eph 2:10).

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.
