John Calvin on Micah 1:6

Though Micah intended especially to devote his services to the Jews, as we have said yesterday, he yet, in the first place, passes judgment on Samaria; for it was his purpose afterwards to speak more fully against Jerusalem and the whole of Judea. And this state of the case ought to be borne in mind; for the Prophet does not begin with the Israelites, because he directs his discourse peculiarly to them; but his purpose was briefly to reprove them, and then to address more especially his own people, for it was for this purpose that he was called. Now, as he threatens destruction to Samaria and the whole kingdom of Israel on account of their corrupted forms of worship, we may hence learn how displeasing to God is superstition, and that he regards nothing so much as the true worship of his name. There is no reason here for men to advance this position — that they do not designedly sin; for God shows how he is to be worshipped by us. Whenever, then, we deviate in any thing from the rule which he has prescribed, we manifest, in that particular, our rebellion and obstinacy. Hence the superstitious ever act like fools with regard to God, for they will not submit to his word, so as to be thereby alone made wise.

And he says, I will set Samaria as an heap of the field, that is, such shall be the ruins that they shall differ nothing from the heaps of the fields: for husband men, we know, when they find stones in their fields, throw them into some corner, that they may not be in the way of the slough. Like such heaps then, as are seen in the fields, Samaria would be, according to what God declared. He then says, that the place would be empty, so that vines would be planted there; and, in the third place, that its stones would be scattered through the valley; as when one casts stones where there is a wide plain, they run and roll far and wide; so would be the scattering of Samaria according to what the Prophet says, it was to be like the rolling of stones in a wide field. He adds, in the fourth place, I will uncover her foundations, that is, I will entirely demolish it, so that a stone, as Christ says, may not remain on a stone, (Matthew 24:2.) We now perceive the import of the words; and we also perceive that the reason why the Prophet denounces on Samaria so severe a judgment was, because it had corrupted the legitimate worship of God with its own inventions; for it had devised, as we well know, many idols, so that the whole authority of the law had been abolished among the Israelites. It now follows —

Micah 1:7

7. And all the graven images thereof shall be beaten to pieces, and all the hires thereof shall be burned with the fire, and all the idols thereof will I lay desolate: for she gathered it of the hire of an harlot, and they shall return to the hire of an harlot.

7. Et omnia sculptilia פסילים, from פסל, to chip or cut with a tool. They were graven or carved images, made of wood, and overlaid with gold or silver.

“The graven image,” says Bishop Horsley, “Was not a thing wrought in metal by the tool of the workman we should now call an engraver; nor was the molten image an image made of metal. In fact, the graven image and the molten image are the same thing under different names. The images of the ancient idolaters were first cut out of wood by the carpenter, as is very evident from the Prophet Isaiah. This figure of wood was overlaid with plates, either of gold or of silver, or, sometimes perhaps, of an inferior metal. And, in this finished state, it was called a graven image, i.e., a carved image, in reference to the inner solid figure of wood, and a molten, i.e., an overlaid or covered image, in reference to the outward metalline case or covering: and sometimes both epithets are applied to it at once, ‘I will cut off the graven and molten image,’ Nahum 1:14.” See also Deuteronomy 7:25; Isaiah 30:22. — Ed. ejus diruentur, et omnes mercedes ejus exurentur igne (alii transferunt, donaria,) et omnia idola ejus ponam in vastitatem; quia e mercede meretricis congregavit, et ad mercedem meretricis revertentur.
