Isaiah 2:3

“And many people shall go and say, &c.] This is a prophecy of the numerous conversions among the Gentiles in the latter day, and agrees with (<380820>Zechariah 8:20-23) and even the author of the old Nizzachonf39 interprets it of the gathering of the people to the Messiah. Come ye, and let us go up to the mountain of the Lord, and to the house of the God of Jacob; the church of Christ, so called; (see Gill on “<230202>Isaiah 2:2”). This expresses the concern that truly gracious souls have for the house of God, and his worship in it; they go up to it, considering it both as their duty and their privilege; and which they do frequently and constantly, with much spiritual pleasure, though…”

“If the curse foretold against Israel has been literally fulfilled, so shall the promised blessing be literal. We Gentiles must not, while giving them the curse, deny them their peculiar blessing by spiritualizing it. The Holy Ghost shall be poured out for a general conversion then (Jer 50:5; Zac 8:21, Zac 8:23; Joe 2:28). from Jerusalem-- (Luk 24:47) an earnest of the future relations of Jerusalem to Christendom (Rom 11:12, Rom 11:15).”

“And many people shall go - This denotes a prevalent “desire” to turn to the true God, and embrace the true religion. It is remarkable that it speaks of an inclination among them to “seek” God, as if they were satisfied of the folly and danger of their ways, and felt the necessity of obtaining a better religion. In many cases this has occurred. Thus, in modern times, the people of the Sandwich Islands threw away their gods and remained without any religion, as if waiting for the message of life. Thus, too, the pagan not unfreguently come from a considerable distance at missionary stations to be instructed, and to receive the Bible and tracts. Perhaps this is to be extensively the mode in…”

“The law - The new law, the doctrine of the gospel, which is frequently called a law, because it hath the nature and power of a law, obliging us no less to the belief and practice of it, than the old law did. Isaiah 2:4”

“2:3 Human society will undergo changes as people conform to God’s revelation and follow his ways and paths. • Judah received the revelation (teaching . . . word) but did not obey it (1:10-15); however, the nations will be ready to do God’s will.”

“Come ye: Jer 31:6, Jer 50:4, Jer 50:5; Zac 8:20-23 he will teach: Deu 6:1; Psa 25:8, Psa 25:9; Mat 7:24; Luk 11:28; Joh 7:17; Act 10:33; Jam 1:25 for out: Isa 51:4, Isa 51:5; Psa 110:2; Luk 24:47; Act 1:8, Act 13:46-48; Rom 10:18 Isaiah 2:4”

“"And peoples in multitude go and say, Come, let us go up to the mountain of Jehovah, to the house of the God of Jacob; let Him instruct us out of His ways, and we will walk in His paths." This is their signal for starting, and their song by the way (cf., Zac 8:21-22). What urges them on is the desire for salvation. Desire for salvation expresses itself in the name they give to the point towards which they are travelling: they call Moriah "the mountain of Jehovah," and the temple upon it "the house of the God of Jacob." Through frequent use, Israel had become the popular name for the people of God; but the name they employ is the choicer name Jacob, which is the name of affection in the mouth…”
