| Geneva Study Bible In that day shall there be an altar to the LORD in the midst of the land of Egypt, and {t} a pillar at its border to the LORD. (t) There will be evident signs and tokens, that God's religion is there: which manner of speech is taken of the patriarchs and ancient time, when God has not as yet appointed the place, and full manner how he would be worshipped. Wesley's Notes 19:19 An altar - The altar is put for the worship of God, as it is in many places both of the Old and New Testament. And nothing is more common in the prophets than to speak of gospel - worship in the phrases of the law. Pillar - A monument of the true religion. Here also he alludes to the ancient custom of erecting pillars to God. The border - As before, in the midst of it. The meaning is, There shall be evidences of their piety in all places. Jamieson-Fausset-Brown Bible Commentary 19. altar-not for sacrifice, but as the "pillar" for memorial and worship (Jos 22:22-26). Isaiah does not contemplate a temple in Egypt: for the only legal temple was at Jerusalem; but, like the patriarchs, they shall have altars in various places. pillar-such as Jacob reared (Ge 28:18; 35:14); it was a common practice in Egypt to raise obelisks commemorating divine and great events. at the border-of Egypt and Judah, to proclaim to both countries the common faith. This passage shows how the Holy Spirit raised Isaiah above a narrow-minded nationality to a charity anticipatory of gospel catholicity. 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. |
