John Calvin's Bible Commentary
Jeremiah 9:20
He proceeds with the same subject, but adopts another figure. He then somewhat changes the comparison; for he had bidden them before to hire women to excite to mourning by fictitious tears, but he now addresses women in general; as though he had said, that such would be the mourning, that hired lamentations would not be sufficient, for the calamity would touch all hearts, and that mercenary wailing would not be real. Hear, he says, ye women
Why he addresses women may be accounted for in two ways: the softness of women more easily leads them to weep; there may be also here an indirect condemnation of the men, that they were deaf and so hardened that no threatenings terrified them. But the first seems to be the most suitable reason here, provided we still understand that real mourning is opposed to reigned mourning. Then Jeremiah passes from the particular to the general; that is, after having spoken of hired women, he now includes all women; for lamentation would prevail in every city, and also in every house: Hear then, ye women, the word of Jehovah
And he adds, and let your ears receive the word of his mouth He mentions on the one hand the mouth of God, and on the other the ears of women. It seems indeed a redundancy, but the repetition is not superfluous. Had he said only, “Let your ears hear the word of his mouth,” there would have been a redundancy; but he spoke before only of the word of God, and hear ye; now he adds, the mouth of God, and the ears of women. The Prophet no doubt intended to rebuke that hardness which we have often noticed. The word of God was deemed of no moment; hence he says, the mouth of God: as though he had said, “God speaks with you as it were from mouth to mouth: for though he employs my labor, I am yet but his instrument; so that you may easily find out that I declare nothing presumptuously, but faithfully deliver what I have received from him.” We hence see how emphatical is this repetition, which may seem at first sight to be superfluous. The same emphasis belongs to the ears of women; it is as though he had said, that they had been hitherto extremely indifferent, and that it was time for their ears to be attentive.
He adds, And teach your daughters; as though he had said, that such would be the wailing, that it would reach not only the old and the middle-aged, but even young girls, as yet rude and ignorant. And let every one, he says, teach her neighbor lamentation In short, the meaning is, that no women, old or young, would be exempt from this mourning, as all would be implicated in a common sorrow; for God’s judgment would reach every age, sex, and order of men, and would also penetrate into every house.
