(5.) The stars from heaven appeared, or acted at least, on Israel's side (v. 20): The stars in their courses, according to the order and direction of him who is the great Lord of their hosts, fought against Sisera, by their malignant influences, or by causing the storms of hail and thunder which contributed so much to the rout of Sisera's army. The Chaldee reads it, from heaven, from the place where the stars go forth, war was waged against Sisera, that is, the power of the God of heaven was engaged against him, making use of the ministration of the angels of heaven. Some way or other, the heavenly bodies (not arrested, as when the sun stood still at Joshua's word, but going on in their courses) fought against Sisera. Those whom God is an enemy to the whole creation is at war with. Perhaps the flashes of lightning by which the stars fought was that which frightened the horses, so as that they pranced till their very hoofs were broken (v. 22), and probably overturned the chariots of iron which they drew or turned them back upon their owners.
