John Calvin's Bible Commentary
Jeremiah 31:16
Refrain, he says, thy voice from weeping The word is בכה beke: as he had mentioned this word before in the second place, “lamentation, the weeping of bitterness,” so he now repeats the same here, “Refrain thy voice from weeping,” that is, cease to complain and to bewail the death of thy children, and thine eyes from tears The meaning is, that the lamentation of Rachel would not be perpetual. We have said that a dead woman is introduced, but that this is done for the sake of solemnity and effect, so that the Jews, having the matter set as it were before their eyes, might be more touched and moved. But if we wish to understand the meaning of the Prophet without a figure it is this, — that the lamentation would not be perpetual, because the exiles would return, and that the land that had fallen to the lot of the children of Benjamin and of Joseph would again be inhabited.
And he says, for reward shall be to thy work He means that the sorrow of Rachel would at length happily come to an end, so as to produce some benefit. While the faithful, according to Isaiah, were complaining that they were oppressed with grief without hope, they said, “We have been in travail, and brought forth wind:” by these words they meant that they had experienced the heaviest troubles; and then they added, “without fruit,” as though a woman were in travail and suffered the greatest pain and anguish, and brought forth no living, but a dead child, which is sometimes the case. Now a woman who gives birth to a living child rejoices, as Christ says, because a man is born, (John 16:21) but when a woman after long pains brings forth a dead lump or something monstrous, it is an increase of sorrow. So the Prophet says, that the labor of Rachel, that is, of her country, would not be without fruit: there shall then be a reward to thy work The Scripture uses the same way of speaking in 2 Chronicles 15:7, where the Prophet Azariah speaks to the King Asa,
“Act manfully, and let not your hands be weakened, for there shall be a reward to your work.”
Then by work is to be understood trouble or sorrow, and by reward a joyful and prosperous issue. The meaning is, that though the whole country mourned miserably for a time, being deserted and bereaved of its inhabitants, yet the issue would be joyful, for the Lord would restore the exiles, so that the land would be like a mother having a numerous family, and delighting in her children, or in her offspring.
Now, were any one to apply this to satisfactions, he would be doing what is very absurd, as the Papists do, who say that by the punishment which we suffer we are redeemed from eternal death, and that then the vengeance of God is pacified, and satisfaction is made to his justice. But when the Prophet declares that there would be reward to the work, he does not commend the fruits of the punishment by which God chastised his people, as though they were, as they say, satisfactions; but he simply reminds them that their troubles and sorrows would not be useless, for a happier issue than the Jews hoped for would take place. But it is God’s gratuitous gift that there is a reward to our work, that is, when the miseries and calamities which he inflicts on us are made aids to our salvation. For doubtless whatever evils we suffer, they are tokens of God’s wrath; poverty, cold, famine, sterility, disease, and all other evils, are so many curses inflicted by God. When, therefore, there is a reward to our troubles and sorrows, that is, when they produce some benefit or fruit, it is as though God turned darkness into light; for naturally, as I have said, all these punishments are curses. But God promises that he will bless us, so that all these punishments shall turn out for our good and salvation, as Paul tells us in Romans 8:28.
Then he adds, they shall return from the land of the enemy By these words he refers to the restoration of the people, so that Rachel would again see her posterity inheriting the promised land. But there is no reason refinedly to dispute here, whether Rachel rejoiced at the return of her offspring, or whether that calamity was lamented by her; for the Prophet’s object was not to shew whether or not the dead are conscious of our affairs; but he speaks figuratively in order to render what he said more striking and forcible. It follows, —
