17
Let your crying be bitter and express your sorrow fervently, and make your mourning worthy of them. Mourn for one day or two so that there can be no criticism, and then be comforted from your grief.
18
Too much grief can lead to death, and grief in one's heart will sap one's strength.
19
Grief also lingers in misery, and the life of the poor is a curse upon the heart.
20
Don't give your heart over to grief; stay away from it, remembering your own end.
21
Don't forget that there's no coming back; you won't do them any good, and you will hurt yourself.
