Isaiah 66:18
18. know—not in the Hebrew. Rather, understand the words by aposiopesis; it is usual in threats to leave the persons threatened to supply the hiatus from their own fears, owing to conscious guilt: "For I . . . their works and thoughts," &c.; namely, will punish [MAURER].
it shall come—the time is come that I will, &c. [MAURER]. gather . . . nations—against Jerusalem, where the ungodly Jews shall perish; and then the Lord at last shall fight for Jerusalem against those nations: and the survivors (Isa 66:19) shall "see God's glory" (Zec 12:8, 9; 14:1-3, 9). tongues—which have been many owing to sin, being confounded at Babel, but which shall again be one in Christ (Da 7:14; Zep 3:9; Re 7:9, 10).Zechariah 14:16-19
16. every one . . . left— (Isa 66:19, 23). God will conquer all the foes of the Church. Some He will destroy; others He will bring into willing subjection.
from year to year—literally, "from the sufficiency of a year in a year." feast of tabernacles—The other two great yearly feasts, passover and pentecost, are not specified, because, their antitypes having come, the types are done away with. But the feast of tabernacles will be commemorative of the Jews' sojourn, not merely forty years in the wilderness, but for almost two thousand years of their dispersion. So it was kept on their return from the Babylonian dispersion (Ne 8:14-17). It was the feast on which Jesus made His triumphal entry into Jerusalem (Mt 21:8); a pledge of His return to His capital to reign (compare Le 23:34, 39, 40, 42; Re 7:9; 21:3). A feast of peculiar joy (Ps 118:15; Ho 12:9). The feast on which Jesus gave the invitation to the living waters of salvation ("Hosanna," save us now, was the cry, Mt 21:9; compare Ps 118:25, 26) (Joh 7:2, 37). To the Gentiles, too, it will be significant of perfected salvation after past wanderings in a moral wilderness, as it originally commemorated the ingathering of the harvest. The seedtime of tears shall then have issued in the harvest of joy [MOORE]. "All the nations" could not possibly in person go up to the feast, but they may do so by representatives.17. no rain—including every calamity which usually follows in the East from want of rain, namely, scarcity of provisions, famine, pestilence, &c. Rain is the symbol also of God's favor (Ho 6:3). That there shall be unconverted men under the millennium appears from the outbreak of Gog and Magog at the end of it (Re 20:7-9); but they, like Satan their master, shall be restrained during the thousand years. Note, too, from this verse that the Gentiles shall come up to Jerusalem, rather than the Jews go as missionaries to the Gentiles (Isa 2:2; Mic 5:7). However, Isa 66:19 may imply the converse.
18. if . . . Egypt go not up—specified as Israel's ancient foe. If Egypt go not up, and so there be no rain on them (a judgment which Egypt would condemn, as depending on the Nile's overflow, not on rain), there shall be the plague . . . . Because the guilty are not affected by one judgment, let them not think to escape, for God has other judgments which shall plague them. MAURER translates, "If Egypt go not up, upon them also there shall be none" (no rain). Ps 105:32 mentions "rain" in Egypt. But it is not their main source of fertility.
19. punishment—literally, "sin"; that is, "punishment for sin."
