Isaiah 27:12 f. End of the Apocalypse. These verses link on to Isaiah 27:1. The general subject is the restoration of Israel from the Dispersion. The interpretation of Isaiah 27:12 is most uncertain. Perhaps the sense is that from the Euphrates to the Wady el-Arish Yahweh will gather His people, beating out the good grain (that is, the Jews) from the straw (that is, the heathen). The trumpet will sound, and those lost (mg.) in Assyria and outcasts in Egypt will assemble for the worship of Yahweh at Jerusalem.
Isaiah 27:12. beat off: like olive berries from the tree (Isaiah 17:6; Isaiah 24:13), but perhaps more probably beat out, i.e. like grain from the ear. flood: the word also means ear of corn.
