Woe to the idol shepherd,.... Or, "the shepherd of nothing" ; that is, no true shepherd, that is good for nothing, for an idol is nothing in the world, 1Co 8:4 and who is an idol himself, sits in the temple of God, and is worshipped as if he was God.
2Th 2:4 and is an encourager and defender of idolatry:that leaveth the flock; has no regard to its spiritual concerns; does not feed it, but fleece it, and leaves it to the cruelty and avarice of his creatures under him:the sword [shall be] upon his arm; with which he should feed the flock:and upon his right eye; with which he should watch over it:his arm shall be clean dried up; his power shall be taken away from him; the antichristian states, which supported him, shall withdraw from him; the ten kings shall hate the whore, strip her naked, eat her flesh, and burn her with fire, Re 17:16:and his right eye shall be utterly darkened; not only given up to judicial blindness, which has been always his case; but his kingdom shall be full of darkness, Re 16:10 his hidden things of darkness shall be exposed; all his crafty schemes will be confounded; and all his wit, cunning, and subtlety, will cease; and everything desirable to him will be taken away from him.
His "arm" may denote his secular power, which shall be taken away from him: and his "right eye" his knowledge of the Scriptures, judgment in controversies, and infallibility pretended to by him, which wilt cease, even in the opinion of men.
