For in death there is no remembrance of thee: in the grave who shall give thee thanks?
6:4 Return: This is a usual part of a petition of a Psalm of lament (Psalm 13). This shows the faith that is required on the part of the recipient. for Thy mercies' sake: Praise for the Lord for His mercy. It is new everyday (Lamentations 3:22,23). His love is always loyal. For in death: When one dies, another one is born and the circle of life goes on. in the grave: After David dies, he will no longer be able to sing unto his God. While alive, David's life can praise the Lord. He can shout and testify to God's love and mercy (94:17).
