The great trumpet shall be blown... — The symbolism had a probable origin in the silver trumpets which were used in the journeys of the Israelites “for the calling of the assembly and for the journeying of the camps” (Numbers 10:1-10), and which were solemnly blown in the year of Jubilee on the eve of the Day of Atonement (Leviticus 25:9). It re-appears in the Apocalyptic eschatology of Matthew 24:31; 1 Corinthians 15:52; 1 Thessalonians 4:16, standing there, as here, for any great event that heralds the fulfilment of a Divine purpose. That purpose, in this instance, is the proclamation of the Year of Redemption, the restoration of the dispersed of Israel from the countries of their exile, of which, as in Isaiah 11:11; Isaiah 19:23, Assyria and Egypt are the two chief representatives. (Comp. Zephaniah 3:10.)
