[15] O LORD, thou knowest: remember me, and visit me, and revenge me of my persecutors; take me not away in thy longsuffering: know that for thy sake I have suffered rebuke. [16] Thy words were found, and I did eat them; and thy word was unto me the joy and rejoicing of mine heart: for I am called by thy name, O LORD God of hosts. [17] I sat not in the assembly of the mockers, nor rejoiced; I sat alone because of thy hand: for thou hast filled me with indignation. [18] Why is my pain perpetual, and my wound incurable, which refuseth to be healed? wilt thou be altogether unto me as a liar, and as waters that fail?
