'Mighty' in the Bible

For I have bent Judah for me, I have filled the bow with Ephraim; and I will raise up thy sons, O Zion, against thy sons, O Greece, and make thee like the sword of a mighty man.

And they shall be as mighty men, treading down the mire of the streets in the battle; and they shall fight, for Jehovah is with them, and the riders on horses shall be put to shame.

And they of Ephraim shall be like a mighty man, and their hearts shall rejoice as through wine; and their children shall see it, and rejoice; their heart shall be joyful in Jehovah.
