'Persecutors' in the Bible

Jehovah, thou knowest: remember me, and visit me, and avenge me of my persecutors; in thy long-suffering take me not away: know that for thy sake I bear reproach.

But Jehovah is with me as a mighty terrible one; therefore my persecutors shall stumble and shall not prevail; they shall be greatly ashamed, for they have not prospered: it shall be an everlasting confusion that shall not be forgotten.
