Behold, for peace I had great bitterness: but thou hast in love to my soul delivered it from the pit of corruption: for thou hast cast all my sins behind thy back.
(Isaiah 38:17-18) KJV
For the grave cannot praise thee, death can not celebrate thee: they that go down into the pit cannot hope for thy truth.
