'Mighty' in the Bible

For indeed I bend Judah as a bow for me. I have filled the bow with Ephraim; and I will stir up your sons, Zion, against your sons, Greece, and will make you like the sword of a mighty man.

They shall be as mighty men, treading down muddy streets in the battle; and they shall fight, because Yahweh is with them; and the riders on horses will be confounded.

Ephraim will be like a mighty man, and their heart will rejoice as through wine; yes, their children will see it, and rejoice. Their heart will be glad in Yahweh.
