'Hero' in the Bible

For I have trodden for Me Judah, A bow I have filled with Ephraim, And I have stirred up thy sons, O Zion, Against thy sons, O Javan, And I have set thee as the sword of a hero.

And Ephraim hath been as a hero, And rejoiced hath their heart as wine, And their sons see, and they have rejoiced, Rejoice doth their heart in Jehovah.

Sword, awake against My shepherd, And against a hero -- My fellow, An affirmation of Jehovah of Hosts. Smite the shepherd, and scattered is the flock, And I have put back My hand on the little ones.
