Psalm 42:9

7Deep calleth unto deep at the noise of thy waterspouts: all thy waves and thy billows are gone over me.

8Yet the LORD will command his lovingkindness in the day time, and in the night his song shall be with me, and my prayer unto the God of my life.

9I will say unto God my rock, Why hast thou forgotten me? why go I mourning because of the oppression of the enemy?

10As with a sword in my bones, mine enemies reproach me; while they say daily unto me, Where is thy God?

11Why art thou cast down, O my soul? and why art thou disquieted within me? hope thou in God: for I shall yet praise him, who is the health of my countenance, and my God.
