(23) Because they have committed villany . . .--The Hebrew noun is almost always used for sins of impurity. It is more commonly rendered "folly" (comp. Genesis 34:7; Deuteronomy 22:21; Judges 19:23-24). The English word "villainy" is used definitely with this meaning by Bishop Hall (Sat. i. 9).

Even I know, and am a witness, saith the Lord.--The words find an echo in Malachi 3:5. We are left to conjecture whether the prophet refers his own knowledge of the facts to a direct supernatural source, or had received private information from his friends at Babylon. The special stress laid on the Lord's knowledge of their guilt suggests the thought that the false prophets with their restricted ideas of God had persuaded themselves that Jehovah the God of Israel hardly exercised his attributes of power in a distant place like Babylon. There they might sin without fear of detection or of punishment. They thought of him as a God not nigh at hand, but far off (Jeremiah 23:23).

Verse 23. - An important and melancholy addition to our knowledge of these false prophets. They were not only misleading prophets, but immoral men in their private capacities. Villainy; rather, folly, as the word is always rendered elsewhere. The phrase "to commit folly in Israel" is always (except Joshua 7:15) used of sins of unchastity.

29:20-32 Jeremiah foretells judgments upon the false prophets, who deceived the Jews in Babylon. Lying was bad; lying to the people of the Lord, to delude them into a false hope, was worse; but pretending to rest their own lies upon the God of truth, was worst of all. They flattered others in their sins, because they could not reprove them without condemning themselves. The most secret sins are known to God; and there is a day coming when he will bring to light all the hidden works of darkness. Shemaiah urges the priests to persecute Jeremiah. Their hearts are wretchedly hardened who justify doing mischief by having power to do it. They were in a miserable thraldom for mocking the messengers of the Lord, and misusing his prophets; yet in their distress they trespass still more against the Lord. Afflictions will not of themselves cure men of their sins, unless the grace of God works with them. Those who slight the blessings, deserve to lose the benefit of God's word, like Shemaiah. The accusations against many active Christians in all ages, amount to no more than this, that they earnestly counsel men to attend to their true interest and duties, and to wait for the performance of God's promises in his appointed way.Because they have committed villany in Israel,.... Or "folly" (f); as the sins of adultery, and prophesying falsely, are afterwards mentioned. This was not the reason why the king of Babylon put them to death; though the Jews (g) have a tradition that they attempted the chastity of Nebuchadnezzar's daughter, for which reason he case them into a furnace; but rather it was on account of their prophesying immediate destruction to Babylon; and telling the captives that they should be delivered in a short time; and stirring them up to prepare to go to their own land; but the reasons here given are those which moved the Lord to deliver them into the hands of the king of Babylon for their destruction:

and have committed adultery with their neighbours' wives; which was a piece of villany, as well as folly; and which abundantly showed that these men were not the prophets of the Lord, or were sent by him, being such impure wretches:

and have spoken lying words in my name, which I have not commanded them; as that the people should return to their own land in a short time; this was another part of their villany and folly, and for which they were given up into the hands of the king of Babylon, to be punished:

even I know, and am a witness, saith the Lord; for though their adulteries might be very secretly committed, and their lying prophecies were not seen to be such by the people in common; yet God, who is omniscient, saw all their impurity, and knew all their lies and falsehood, and was, and would be, a swift witness against them, here and hereafter. The Targum is,

"and before me it is manifest, and my word is a witness, saith the Lord.''
