Zephaniah 1:16

Besides the supernatural terrors of the judgment there is the hostile assault which the supernatural terrors accompany.

A day of the trumpet and alarm The "trumpet" was blown amidst the attack (Judges 7:19), as now martial music accompanies the advance. Amos 2:2, "Moab shall die with tumult, with shouting, and with the sound of the trumpet." The word "alarm" here is that rendered "shouting," Amos 1:14; Amos 2:2, in accordance with its literal sense "to arms!" (Ital. all" arme). The "shouting" (terû-ah), originally that of battle (Jeremiah 4:19), became in later and more peaceful times the shout of the glad worshippers on the feast days (Ezra 3:11-13).
