Joel 2:1

Blow. The prophets often ordered, to signify what will take place. (Worthington) --- The people were gathered by the sound of trumpets. The danger from the locusts was imminent; and all are exhorted to avert it, by praying in the temple, &c. --- Tremble at the sound, Amos iii. 6. (Calmet) --- Extemplo turbati. (Virgil, \'c6neid viii.) --- Lord. That is, the time when he will execute justice on sinners, (Challoner) and suffer affliction to fall upon them. (Worthington) (Chap. i. 15.)
