Isaiah 27:6

“He shall cause them that come of Jacob to take root, &c.] That is, the posterity of Jacob, the seed of Israel, in a spiritual sense; such who are Israelites indeed, in whom there is no guile; these shall be so far from being plucked up, or rooted out of the vineyard, the church, that they shall take deeper root, and their roots shall spread yet more and more; they shall be rooted and grounded in the love of God, and also in Christ, and be built up in him, as well as firmly settled and established in the church, (<490317>Ephesians 3:17 <510207>Colossians 2:7) or, “them that come to Jacobf531”; proselytes unto him, converted Gentiles, that come to the church of Christ, signified by “Jacob”,…”

“He--Jehovah. Here the song of the Lord as to His vineyard (Isa 27:2-5) ends; and the prophet confirms the sentiment in the song, under the same image of a vine (compare Psa 92:13-15; Hos 14:5-6). Israel . . . fill . . . world-- (Rom 11:12).”

“Take root - To be firmly settled in their possessions. Fruit - Their posterity shall seek habitations in other countries, and replenish them with people. But this seems to be understood of the spiritual seed of Jacob. Isaiah 27:7”

“27:6 Jacob’s descendants will take root and the remnant will increase (37:31; cp. 5:24; 14:30; for application to the Messiah, see 11:1, 10). • fill the whole earth: The fulfillment of this prophecy extends beyond the restoration of Israel from exile to the second coming of the Lord Jesus. It includes all the righteous children of God—Jews and Gentiles—who suffer but remain obedient as they wait for the fullness of redemption (see 26:18; John 15:1-8).”

“Isa 6:13, Isa 37:31, Isa 49:20-23, Isa 54:1-3, Isa 60:22; Psa 92:13-15; Jer 30:19; Hos 2:23, Hos 14:5, Hos 14:6; Zac 2:11, Zac 10:8, Zac 10:9; Rom 11:16-26; Gal 3:29; Phi 3:3; Rev 11:15 Isaiah 27:7”

“The prophet now adds to the song of the vineyard, by way of explanation. "In future will Jacob strike roots, Israel blossom and bud, and fill the surface of the globe with fruits." We may see from הבּאים (acc. temp. as in Ecc 2:16, equivalent in meaning to "Behold, the days come," Jer 7:32, etc.), that the true language of prophecy commences again here. For the active וּמלאוּ, compare Jer 19:4; Eze 8:17, etc. The prophet here says, in a figure, just the same as the apostle in Rom 11:12, viz., that Israel, when restored once more to favour as a nation, will become "the riches of the Gentiles." Isaiah 27:7”
