Jeremiah 16:5-9:

5 “For thus says the LORD: Do not enter the house of mourning, or go to lament or grieve for them, for I have taken away my peace from this people, my steadfast love and mercy, declares the LORD.
6 Both great and small shall die in this land. They shall not be buried, and no one shall lament for them or cut himself or make himself bald for them.
7 No one shall break bread for the mourner, to comfort him for the dead, nor shall anyone give him the cup of consolation to drink for his father or his mother.
8 You shall not go into the house of feasting to sit with them, to eat and drink.
9 For thus says the LORD of hosts, the God of Israel: Behold, I will silence in this place, before 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.

Ecclesiastes 7:1-4:

1 A good name is better than precious ointment, and the day of death than the day of birth.
2 It is better to go to the house of mourning than to go to the house of feasting, for this is the end of all mankind, and the living will lay it to heart.
3 Sorrow is better than laughter, for by sadness of face the heart is made glad.
4 The heart of the wise is in the house of mourning, but the heart of fools is in the house of mirth.
