'Mighty One' in the Bible

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.

Wherefore have I seen it? they are dismayed and are turned backward; and their mighty ones are beaten down, and are fled apace, and look not back: terror is on every side, saith Jehovah.
