I am forgotten as a dead man out of mind: I am like a broken vessel.
forgotten ... out of mind. So Deuteronomy 31:21, "forgotten out of the months."
As ... dead - (Psalms 88:4-5; Ecclesiastes 9:5.)
A broken vessel - for which no one cares, since it can never be made whole again, therefore thrown away as worthless. Compare Romans 9:22; Psalms 2:9; Jeremiah 18:4; Jeremiah 48:38; Hosea 8:8.
