II. The proof of this. No witnesses need be called; it is proved by the notorious evidence of the facts. 1. They went about to deny it, and were ready to plead, Not guilty. They pretended that they would acquit themselves from this guilt, they washed themselves with nitre, and took much soap, offered many things in excuse and extenuation of it, v. 22. They pretended that they did not worship these as gods, but as demons, and mediators between the immortal God and mortal men, or that it was not divine honour that they gave them, but civil respect; thus they sought to evade the convictions of God's word and to screen themselves from the dread of his wrath. Nay, some of them had the impudence to deny the thing itself; they said, I am not polluted, I have not gone after Baalim, v. 23. Because it was done secretly, and industriously concealed (Ezek. viii. 12), they thought it could never be proved upon them, and they had impudence enough to deny it. In this, as in other things, their way was like that of the adulterous woman, that says, I have done no wickedness, Prov. xxx. 20. 2. Notwithstanding all their evasions, they are convicted of it and found guilty: "How canst thou deny the fact, and say, I have not gone after Baalim? How canst thou deny the fault, and say, I am not polluted?" The prophet speaks with wonder at their impudence: "How canst thou put on a face to say so, when it is certain?" (1.) "God's omniscience is a witness against thee: Thy iniquity is marked before me, saith the Lord God; it is laid up and hidden, to be produced against thee in the day of judgment, sealed up among his treasures," Deut. xxxii. 34; Job xxi. 19; Hos. xiii. 12. "It is imprinted deeply and stained before me;" so some read it. "Though thou endeavour to wash it out, as murderers to get the stain of the blood of the person slain out of their clothes, yet it will never be got out." God's eye is upon it, and we are sure that his judgment is according to truth. (2.) "Thy own conscience is a witness against thee. See thy way in the valley" (they had worshipped idols, not only on the high hills, but in the valleys, Isa. lvii. 5, 6), in the valley over-against Beth-peor (so some), where they worshipped Baal-peor (Deut. xxxiv. 6, Num. xxv. 3), as if the prophet looked as far back as the iniquity of Peor; but, if it mean any particular valley, surely it is the valley of the son of Hinnom, for that was the place where they sacrificed their children to Moloch and which therefore witnessed against them more than any other: "look into that valley, and thou canst not but know what thou hast done."
