Psalms 76:5,6 - Joseph Benson’s Commentary on the Old and New Testaments

The stout-hearted are spoiled Of all that glory and advantage which they either had already obtained, or further expected from the success of their present expedition. They became a prey to those on whom they hoped to prey. They have slept their sleep Even a perpetual sleep, or the sleep of death. They have slept so as never to awake again to life on earth. He terms their death sleep, because they were slain in the night, when they had composed themselves to sleep, and so passed, perhaps insensibly, from one sleep to another. None of the men of might have found their hands They had no more strength in, or use of their hands, against the destroying angel, than those who have no hands. At thy rebuke, O God of Jacob By a rebuking blast sent from thee; both the chariot and horse are cast into a dead sleep Are rendered motionless and useless, like persons in a dead sleep. The horses were killed, as well as their riders, and the chariots were of no further service.
