He must shave off the hair of his head and beard (v. 1), which signified God's utter rejecting and abandoning that people, as a useless worthless generation, such as could well be spared, nay, such as it would be his honour to part with; his judgments, and all the instruments he made use of in cutting them off, were this sharp knife and this razor, that were proper to be made use of, and would do execution. Jerusalem had been the head, but, having degenerated, had become as the hair, which, when it grows thick and long, is but a burden which a man wishes to get clear of, as God of the sinners in Zion. Ah! I will ease me of my adversaries, Isa. i. 24. Ezekiel must not cut off that hair only which was superfluous, but cut it all off, denoting the full end that God would make of Jerusalem. The hair that would not be trimmed and kept neat and clean by the admonitions of the prophets must be all shaved off by utter destruction. Those will be ruined that will not be reformed.
