Mourn
In a general sense, mourning in the Bible represents a state of grief over the lack of desires for good and true ideas about life. This often happens when a church or an aspect of a church has fallen away from the Lord and has been devastated. It can also be when a new church or state of a church is soon to begin, and there is nothing yet in place. In particular, especially when paired with "weeping," "mourning" has do with the loss of all desire for good and the presence of evil; "weeping" in those cases has to do with the devastation of thought and knowledge.
Genesis 2:3-7
3
And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
4
These are the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens,
5
And every plant of the field before it was in the earth, and every herb of the field before it grew: for the LORD God had not caused it to rain upon the earth, and there was not a man to till the ground.
6
But there went up a mist from the earth, and watered the whole face of the ground.
7
And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
