Albert Barnes Commentary Jeremiah 16:7

"neither shall men break [bread] for them in mourning, to comfort them for the dead; neither shall men give them the cup of consolation to drink for their father or for their mother." — Jeremiah 16:7 (ASV)

Tear themselves - Better as in the margin; “break broad for them.” It was customary upon the death of a relative to fast, and for the friends and neighbors after a decent delay to come and comfort the mourner, and urge food upon him (2 Samuel 12:17); food was also distributed at funerals to the mourners, and to the poor.

Cup of consolation - Marginal reference note.
