Zechariah 13:2

I will cut off the names of the idols I will utterly destroy idols and idolatry. The Jews were forbidden to mention the names of the heathen idols, Exodus 23:13; Joshua 23:7; and when idolatry should be utterly extirpated, the names of the idols should be buried in oblivion. “It has been urged, in proof that this prophecy was uttered before the Babylonish captivity, that idolatry and groundless pretensions to prophecy were common among the Jews at that time, which has not been the case since. But, admitting the Jews not to have been addicted to idolatry, or false prophesying, at any particular period, [since the Babylonish captivity,] who can say they will not fall into both those transgressions at some future time? It is probable they will do so; for Ezekiel, confessedly prophesying of the latter times, when Israel and Judah, incorporated again into one nation, shall return into their own land, says, to the same effect as Zechariah, Neither shall they defile themselves any more with their idols, nor with their detestable things, nor with any of their transgressions, Ezekiel 37:23. But besides, supposing the Jews themselves to remain untainted with those corruptions, it surely will not be denied that they do and may still prevail among other nations, who may be included in the term הארצ, taken in its most general sense, the earth; and so I conceive it should be: for we are taught to expect that the conversion of the Jews will be followed by a further reformation in the world, Romans 11:15; and that the time will come, when the kingdoms of this world shall become the kingdoms of our God and of his Christ, Revelation 11:15; and the beast, the emblem of idolatry, and with him the false prophet, shall be cast into a lake of fire and brimstone, Revelation 19:2.” Blayney. I will cause the prophets The false prophets; and unclean spirit This seems to mean those that prophesy by means of an unclean spirit: see Acts 16:16; Revelation 16:13; and what is said in the next verse of any one that shall prophesy, must be understood of those that undertake to prophesy by means of an impure spirit, or other false pretences.
