John Calvin on Jeremiah 16:8

Here the Prophet refers to other feasts, where hilarity prevailed. The meaning then is, — that the people were given up to destruction, so that nothing was better than to depart from them as far as possible. So Jeremiah is prohibited from going at all to them, so that he might not be their associate either in joy or in sorrow; as though he had said, — ‘Have no more anything to do with this people; if they lament their dead, leave them, for they are unworthy of any act of kindness; and if they make joyful feasts, be far from them, for every intercourse with them is accursed.” We now then understand why the Prophet spoke of grief, lamentation and mourning, and then mentioned joy. He afterwards adds, —

Jeremiah 16:9

9. For thus saith the LORD of hosts, the God of Israel; Behold, I will cause to cease out of this place in your eyes, and in your days, the voice of mirth, and the voice of gladness, the voice of the bridegroom, and the voice of the bride.

9. Quoniam sic dixit Jehova exercituum, Deus Israel, Ecce ego auferens ab hoc loco, coram oculis vestris, et in diebus vestris, vocem gaudii et vocem laetitiae, vocem sponsi et vocem sponsae.
