Isaiah 2:5

“O house of Jacob, &c.] This is either an exhortation of the prophet to the men of his generation, to attend to the light of the law, which the Lord had given them, as Aben Ezra and Kimchi; or rather, as the Targum and Jarchi suggest, an exhortation of the nations to the people of Israel, and are indeed the words of the converted Gentiles to the people of the Jews, being concerned for their conversion and spiritual welfare, as will appear in the latter day; when they will not only encourage one another to go up to the house of the Lord, as in the preceding verses, but will be very solicitous that the Jews, the posterity of Jacob, share with them in all that light and glory that shall be risen…”

“The connection is: As Israel's high destiny is to be a blessing to all nations (Gen 12:3), let Israel's children walk worthy of it (Eph 5:8).”

“O house of Jacob - This is a direct address, or exhortation, of the prophet to the Jews. It is made in view of the fact that God had gracious purposes toward them. He intended to distinguish them by making them the source of blessings to all nations. As this was to be their high destiny, he exhorts them to devote themselves to him, and to live to his honor. The word “house” here means the “family, or nation.” The phrase is applied to the Jews because their tribes were descended from the twelve sons of Jacob. Let us walk - Let us “live.” The word “walk” is often used to denote human life or conduct; compare Isaiah 2:3; Romans 6:4; Romans 8:1; 1 Corinthians 5:7; Galatians 6:16, ... In the…”

“The light - Take heed that you do not reject that light which is so clear that even the blind Gentiles will discern it. Isaiah 2:6”

“2:5–4:1 Isaiah condemned Israel’s and Judah’s arrogance and self-exaltation, warning them that only God was to be exalted. All attempts by humans to lift themselves up will actually result in humiliation. 2:5-22 The prophet threatened judgment and scoffed at human pride. All human structures (religious, economic, military, social) will come under divine scrutiny and be found deficient on the day of the Lord—that final day in history when God will judge the wicked once and for all (1 Cor 1:8; 1 Thes 5:2; 2 Thes 2:2; 2 Pet 3:10; Rev 20:7-15). At times, the prophets also used the expression “the day of the Lord” (or others like it, such as “that day”) to refer to special instances of God’s…”

“come ye: Isa 2:3, Isa 50:10, Isa 50:11, Isa 60:1, Isa 60:19; Psa 89:15; Luk 1:79; Joh 12:35, Joh 12:36; Rom 13:12-14; Eph 5:8; Th1 5:5, Th1 5:6; Jo1 1:7; Rev 21:23, Rev 21:24 Isaiah 2:6”

“Isaiah presents himself to his contemporaries with this older prophecy of the exalted and world-wide calling of the people of Jehovah, holds it up before them as a mirror, and exclaims in Isa 2:5, "O house of Jacob, come, let us walk in the light of Jehovah." This exhortation is formed under the influence of the context, from which Isa 2:2-4 are taken, as we may see from Mic 4:5, and also of the quotation itself. The use of the term Jacob instead of Israel is not indeed altogether strange to Isaiah ( Isa 8:17; Isa 10:20-21; Isa 29:23), but he prefers the use of Israel (compare Isa 1:24 with Gen 49:24).With the words "O house of Jacob" he now turns to his people, whom so glorious a future…”
