The sorrows of a travailing woman will come on him. He is an unwise son; For when it is time, he doesn't come to the opening of the womb.
It must be noticed, that the Prophet alludes to the time of birth; for he had said before, that the sorrows of one in travail would come on the people of Israel; he now declares that these sorrows would be filial. Though a woman be in labour and in great danger in giving birth, she is yet freed in a moment, and as Christ says, joy and gladness arise from that sorrow, (John 16:21.) But the Prophet says that this bringing forth would be very different; for it would be an abortion, and the child would be retained to putrefy in the womb. If a woman in the very birth restrains effort and shrinks in her strength, she destroys the child and herself at the same time; for she cannot bring forth without exertion. Since then the safety of the woman depends on the exertion made, the Prophet now says, that the contrary would be the case with the people of Israel. They are, he says, like a woman in travail; but they are at the same time blinded with folly, for they retain the child in the womb and make no effort: so this parturition must at last be fatal to them. Why? Because they make no effort to bring forth the child.
