Go and tell Hananiah, saying, thus saith the Lord,.... Whose name he had abused; whose prophet he had ill treated; and whose prophecies he had contradicted, and the symbols of them had contumeliously used: thou hast broken the yokes of wood: or, "bonds", or "the thongs" (q); with which the yokes of wood were bound and fastened, as Kimchi interprets it: but thou shall make for them yokes of iron; not Hananiah, but Jeremiah; who should prophesy of a more severe bondage the nations should be brought into by Nebuchadnezzar, in direct contradiction to Hananiah's prophecy; instead of wooden yokes, they should have iron ones; which should lie heavier, and bear harder upon them, and which could not be broken nor taken off. (q) "lora lignea", Junius & Tremellius.
