John Wesley on Deuteronomy 27:4

Mount Ebal - The mount of cursing. Here the law is written, to signify that a curse was due to the violators of it, and that no man could expect justification from the works of the law, by the sentence whereof all men are justly accused, as being all guilty of the transgression of it in one kind and degree or other. Here the sacrifices are to be offered, to shew that there is no way to be delivered from this curse, but by the blood of Christ, which all these sacrifices did typify, and by Christ's being made a curse for us.
