'Mourning' in the Bible

They do not cry out to Me from their heartWhen they wail on their beds [in unbelieving despair];For the sake of grain and new wine they assemble themselves [as if worshiping Baal];They rebel against Me.

They will not pour out drink offerings of wine to the Lord; they will not please him with their sacrifices. Their sacrifices will be like bread eaten while in mourning; all those who eat them will make themselves ritually unclean. For their bread will be only to satisfy their appetite; it will not come into the temple of the Lord.
