'Mighty' in the Bible

When I have bent Judah for me, filled the bow with Ephraim, and raised up thy sons, O Zion, against thy sons, O Greece, and made thee as the sword of a mighty man.

And they shall be as mighty men, which tread down their enemies in the mire of the streets in the battle: and they shall fight, because the LORD is with them, and the riders on horses shall be confounded.

And they of Ephraim shall be like a mighty man, and their heart shall rejoice as through wine: yea, their children shall see it, and be glad; their heart shall rejoice in the LORD.

Howl, fir tree; for the cedar is fallen; because the mighty are spoiled: howl, O ye oaks of Bashan; for the forest of the vintage is come down.
