The idols have spoken vanity - This is spoken of the Jews, and must refer to their idolatry practiced before the captivity, for there were no idols after.
Therefore they went their way - They were like a flock that had no shepherd, shifting from place to place, and wandering about in the wilderness, seeking for pasture, wherever they might find it. Some think that the idols and diviners were those of the Seleucidae Greeks, who excited their masters with promises of success against the Maccabees. Others think that the Babylonish captivity is foretold; for a determined future event is frequently spoken of by the prophets as past.
For the teraphim have spoken vanity - Rather, “spake vanity.” He appeals to their former experience. Their father had sought of idols, not of God; therefore they went into captivity. The “teraphim” were used as instruments of divination. They are united with the “ephod,” as forbidden, over against the allowed, means of enquiry as to the future, in Hosea, “without an ephod and without teraphim” Hosea 3:4; they were united in the mingled worship of Micah Judges 17:5; Judges 18:14, Judges 18:17-18, Judges 18:20; Josiah “put” them “away” together with the “workers with familiar spirits and the wizards” 2 Kings 23:24, to which are added, “the idols.” It was probably, a superstition of Eastern origin. Rachel brought them with her from her father‘s house, and Nebuchadnezzar used them for divination. Ezekiel 21:21. Samuel speaks of them, apparently, as things which Saul himself condemned. “Rebellion is as the sin of divination, and stubbornness as iniquity or idolatry, and teraphim” 1 Samuel 15:23. For it was probably in those his better days, that “Saul had put away those that had familiar spirits and wizards out of the land” 1 Samuel 28:3. Samuel then seems to tell him, that the sins to which he clave were as evil as those which he had, in an outward zeal, like Jehu, condemned. Anyhow, the “teraphim” stand united with the “divination” which was expressly condemned by the law Deuteronomy 18:13-14. The use of the teraphim by Rachel Genesis 31:19, Genesis 31:34-35 and Michal 1 Samuel 19:13, 1 Samuel 19:16 (for whatever purpose) implies that it was some less offensive form of false worship, though they were probably the “strange gods” Genesis 35:2, Genesis 35:4 which Jacob bade his household to put away, or, anyhow, among them, since Laban calls them, “my gods” Genesis 31:30, Genesis 31:32.
Zechariah uses anew the words of Jeremiah and Ezekiel, “Hearken ye not to your prophets, nor to your diviners, nor to your dreamers, nor to your enchanters, nor to your sorcerers” Jeremiah 27:9; and, “let not your prophets and your diviners, that be in the midst of you, deceive you, neither hearken to your dreams, which ye cause to be dreamed” Jeremiah 29:8; and Ezekiel, “While they see vanity unto thee, while they divine a lie unto thee” (Ezekiel 21:29; add Ezekiel 22:28). The words not only joined on the prophet‘s warning with the past, but reminded them of the sentence which followed on their neglect. The echo of the words of the former prophets came to them, floating, as it were, over the ruins of the former temple.
Therefore they went their way as a flock - Which, having no shepherd, or only such as would mislead them, removed, but into captivity. “They were troubled.” The trouble lasted on, though the captivity ended at the appointed time. Nehemiah speaks of the exactions of former governors, “The former governors which were before me, laid heavy weights upon the people, and took from them in bread and wine, after forty shekels of silver; also their servants used dominion over the people; and I did not so, because of the fear of God” Nehemiah 5:15.
Because there was no shepherd - As Ezekiel said of those times, “They were scattered, because there is no shepherd; and they became meat to all the beasts of the field, when they were scattered: My flock was scattered upon all the face of the earth; and none did search or seek after them” Ezekiel 34:5-6.
