Isaiah 60:20
Thy sun shall no more go down; neither shall thy moon withdraw itself: for the LORD shall be thine everlasting light, and the days of thy mourning shall be ended.

Ecclesiastes 7:1-3
A good name [is] better than precious ointment; and the day of death than the day of one's birth.
[It is] better to go to the house of mourning, than to go to the house of feasting: for that [is] the end of all men; and the living will lay [it] to his heart.
Sorrow [is] better than laughter: for by the sadness of the countenance the heart is made better.

2 Samuel 12:21-23
Then said his servants unto him, What thing [is] this that thou hast done? thou didst fast and weep for the child, [while it was] alive; but when the child was dead, thou didst rise and eat bread. And he said, While the child was yet alive, I fasted and wept: for I said, Who can tell [whether] GOD will be gracious to me, that the child may live? But now he is dead, wherefore should I fast? can I bring him back again? I shall go to him, but he shall not return to me.

2 Corinthians 1:3-4
Blessed [be] God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God.
