15 O LORD, thou knowest: remember me, and visit me, and avenge me of my persecutors; take me not away in thy long-suffering: know that for thy sake I have suffered rebuke.
16 Thy words were found, and I did eat them; and thy word was to me the joy and rejoicing of my 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 to me as a liar, [and as] waters [that] fail?
19 Therefore thus saith the LORD, If thou shalt return, then will I bring thee again, [and] thou shalt stand before me: and if thou shalt separate the precious from the vile, thou shalt be as my mouth: let them return to thee; but return not thou to them.
