'Mourning' in the Bible

When the time of mourning passed, David had her brought to his palace. She became his wife and she bore him a son. But what David had done upset the Lord.

So Joab sent to Tekoa and brought from there a wise woman. He told her, "Pretend to be in mourning and put on garments for mourning. Don't anoint yourself with oil. Instead, act like a woman who has been mourning for the dead for some time.

Joab was told, "The king is weeping and mourning over Absalom."

So the victory of that day was turned to mourning as far as all the people were concerned. For the people heard on that day, "The king is grieved over his son."
