My days are past, my purposes are broken off, even the thoughts of my heart.
Only do not vainly speak of the restoration of health to me; for "my days are past."
Broken off - as the threads of the web cut off from the loom (Isaiah 38:12).
Thoughts - literally, possessions - i:e., all the feelings and fair hopes which my heart once cherished. These belong to the heart, as "purposed" to the understanding: the two together here describe the entire inner man.
