Isaiah 13:7

Therefore shall all hands be faint, and every man's heart shall melt:

Ver. 7. Therefore shall all hands be faint.] Base fear, that cowardly passion, shall betray them to the enemy, by expectorating their courage, and causing their hearts to fall into their heels, as we say. But this also cometh from the Lord of hosts, who is wonderful in counsel and excellent in working, for he ordereth the armour, Jer 50:25 and he strengtheneth or weakeneth the armies of either party. Eze 30:24 Whencesoever the sword cometh it is "bathed in heaven." Isa 34:5

And every heart shall melt.] How much more shall wicked men's hearts do so at the day of judgment, when the powers of heaven shall be shaken. Luk 21:26 Alegoriae; haec veriora erunt in die iudicii cuius hic est typus.
