Thus saith the LORD of hosts, the God of Israel, saying; Ye and your wives have both spoken with your mouths, and fulfilled with your hand, saying, We will surely perform our vows that we have vowed, to burn incense to the queen of heaven, and to pour out drink offerings unto her: ye will surely accomplish your vows, and surely perform your vows.
Ye ... have both spoken with your mouths, and fulfilled with your hand - ironical praise. They had pleaded their obligation to fulfill their vows in excuse for their idolatry. He answers, no one can accuse you of unsteadiness as to your idolatrous vows; but stedfastness toward God ought to have prevented you from making, or, when made, from keeping such vows.
Ye will surely accomplish your vows. Jeremiah hereby gives them up to their own fatal obstinacy.
