'Persecutors' in the Bible

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.

But the LORD is with me as a mighty terrible one: therefore my persecutors shall stumble, and they shall not prevail: they shall be greatly ashamed; for they shall not prosper: their everlasting confusion shall never be forgotten.
