Psalm 6:4 Meaning

2Have mercy upon me, O LORD; for I am weak: O LORD, heal me; for my bones are vexed.

3My soul is also sore vexed: but thou, O LORD, how long?

4Return, O LORD, deliver my soul: oh save me for thy mercies' sake.

5For in death there is no remembrance of thee: in the grave who shall give thee thanks?

6I am weary with my groaning; all the night make I my bed to swim; I water my couch with my tears.
