“And there shalt thou build an altar unto the LORD thy God, an altar of stones: thou shalt not lift up any iron tool upon them.”
King James Version (KJV)
27:3 This law - The law properly so called, that is, the sum and substance of the precepts or laws of Moses, especially such as were moral, particularly the decalogue. Write it, that thou mayest go in - As the condition of thy entering into the land. For since Canaan is given only by promise, it must be held by obedience.
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.
27:6 Whole stones - Rough, not hewed or polished. By the law written on the stones, God spake to them: by the altar and sacrifices upon it, they spake to God: and thus was communion kept up between them and God.
