Matthew Poole and continuators on Isaiah 9:4

4 For thou hast broken the yoke of his burden , and the staff of his shoulder , the rod of his oppressour , as in the day of Midian .

This notes the Matter and Occasion of the foregoing Joy.

His burdensom and heavy yoke, as the throne of holiness is put for the holy throne, Psal. 47, 8.

Either the Staff wherewith his Shoulders were smitten, or the Staff or Staves by which he was forced to carry Burdens upon his Shoulders.

Wherewith he beat him. Or, the scepter, the Power and Tyranny which he exercised over him.

Of all his Oppressors, but especially of Sin and of the Devil.

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 onely 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.
