Jeremiah 16:4-6

4“They will die of deadly diseases. They will not be mourned or buried; they will be like dung on the surface of the ground and come to an end by sword and famine, and their dead bodies will be food for the birds of the air and for the beasts of the earth.”

5For thus says the Lord, “Do not enter a house of mourning, nor go to lament (express grief) or bemoan [the dead], for I have taken My peace away from this people,” says the Lord, “even My lovingkindness and compassion.
