Isaiah 27:13

Hebrew Key Terms

Context: Isaiah prophesies that "in that day" a great trumpet will sound, gathering Israel's exiles from Assyria and Egypt to worship the LORD at Jerusalem. This eschatological trumpet reverses the scattering caused by judgment, gathering the lost and dispersed to Zion. The "great trumpet" (šôpār gādôl) emphasizes the summons's power and scope—reaching from east (Assyria) to south (Egypt), gathering all scattered Israel.

Connections

Connection Method(s): Promise-Fulfillment, Typology (Providential, Forward-Looking) — Isaiah's prophecy of a great trumpet gathering scattered Israel is fulfilled in Christ's return trumpet that gathers the elect from all nations, with the historical exile-restoration pattern serving as providential type of the eschatological gathering. Sub-label: Forward-Looking is retained here under the donor-signal rule applied across TT 058 (where the festal donors moved to Backward-Looking). Unlike Leviticus 23:24's zikrôn tərûʿâ, Isaiah 27:13 carries a prospective signal in the donor context itself: the oracle is framed בַּיּוֹם הַהוּא ("in that day") with a niphal imperfect yittāqaʿ ("will be blown") — the donor's own grammar projects the trumpet forward to a visitation that has not yet occurred, within Isaiah's new-exodus ingathering material (cf. the ke- of analogy at Isaiah 11:15-16).

Christological Connection: Isaiah 27:13's great trumpet finds ultimate fulfillment in Christ's return when He gathers His elect from all nations. Jesus declares: "He will send out his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of heaven to the other" (Matthew 24:31). Where Assyria and Egypt represented Israel's literal scattering, the church experiences global dispersion—believers scattered throughout every nation, culture, and geography. Christ's trumpet will summon all: "The Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God" (1 Thessalonians 4:16). The "lost" (ʾōbədîm) and "driven out" (niddāḥîm) include those dead in Christ whom death scattered—the trumpet raises them first (1 Thessalonians 4:16). Then living believers are gathered. The result: all God's people assembled, none missing. Revelation pictures this: "A great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb" (Revelation 7:9). The "great trumpet" surpasses all previous trumpets—Sinai's theophanic trumpet, jubilee's liberation trumpet, Feast of Trumpets' memorial trumpet. This is the ultimate, eschatological, resurrection trumpet. The worship goal ("worship the LORD on the holy mountain") finds fulfillment as believers worship eternally in God's presence (Revelation 22:3: "his servants will worship him"). Isaiah's Jerusalem becomes the new Jerusalem descending from heaven (Revelation 21:2). The trumpet's blast is comprehensive—reaching dead in graves, living on earth, scattered across globe—gathering all to Christ in an instant. No believer too remote, no saint too long deceased—the great trumpet summons all to final assembly.
