Lord, when thou wentest out of Seir— The argument of this ode is, the delivery of the people of Israel, by the assistance of God, from bondage; which the sacred writer briefly proposing at the beginning, and having summoned the kings and princes of the neighbouring nations to take note of so great an event, she enters upon the praises of God, not from the recent benefit, but from the miracles performed of old, at their departure out of Egypt.
O JEHOVAH! when thou wentest out of Seir, When thou marched'st out of the land of Edom, The earth trembled; the heavens thundered; The clouds dropt down water.
