Thou hast broken: this notes the matter and occasion of the foregoing joy. The yoke of his burden; his burdensome and heavy yoke, as the throne of holiness is put for the holy throne, Psalms 47:8. The staff of his shoulder; either the staff wherewith his shoulders were smitten, or the staff or staves by which he was forced to carry burdens upon his shoulders. The rod, wherewith he beat him. Or, the sceptre; the power and tyranny which he exercised over him. Of his oppressor; of all his oppressors, but especially of sin and of the devil. As in the day of Midian; when God destroyed the Midianites in so admirable a manner, and by such unlikely and contemptible means, by three hundred men, and they not fighting, but only holding lamps in their hands, and sounding their trumpets; which was an eminent type of Christ's conquering the devil, and all his enemies, by dying upon the cross, and by the preaching of a few unlearned and despicable persons, &c.
