'Persecutors' in the Bible

O Jehovah, thou knowest; remember me, and visit me, and avenge me of my persecutors; take me not away in thy longsuffering: know that for thy sake I have suffered reproach.

But Jehovah is with me as a mighty one and a terrible: therefore my persecutors shall stumble, and they shall not prevail; they shall be utterly put to shame, because they have not dealt wisely, even with an everlasting dishonor which shall never be forgotten.
