Matthew Poole and continuators on Deuteronomy 21:3

3 And it shall be that the city which is next unto the slain man, even the elders of that city shall take an heifer which hath not been wrought with, and which hath not drawn in the yoke .

A fit vicegerent and representative of the muderer, in whose stead it was kild, who by this act hath shewn himself to be a son of Belial, who would not bear the yoke of Gods law. A type also of Christ, who was obliged to no work and under no yoke, but what he had voluntarily taken upon himself.
