John Gill Commentary Psalms 83:15

"So pursue them with thy tempest, And terrify them with thy storm." — Psalms 83:15 (ASV)

So persecute them with your tempest
Pursue them with your fury, follow them with your vengeance; cause it to fall upon them like a mighty tempest:

and make them afraid with your storm ;
God has his storms and tempests of wrath and vengeance, which he sometimes causes to fall upon wicked men in this life, to their inexpressible terror, and with which he takes them out of this world; and he has still more horrible ones to rain upon them hereafter: see (Job 27:20Job 27:21) (Psalms 11:6) .
