Job 38:23 - Matthew Poole's English Annotations on the Holy Bible

Which, i.e. which snow, and especially hail. Against the time of trouble, i.e. when I intend to bring trouble or calamity upon any country or people for their sins, or for their trial. Or, against the time of the enemy, i.e. when I intend to punish mine or my people's enemies, and to fight against them with these weapons; of which see instances Exodus 9:14 Joshua 10:11. Compare 1 Samuel 7:10 Job 36:31 Isaiah 30:30.
