'Mighty One' in the Bible

For this says the lord Jehovah of armies, the mighty one of Israel, Wo! I will take vengeance of mine adversaries, and I will avenge myself of mine enemies:

For they shall be ashamed of their mighty ones which ye desired, and ye shall blush for the gardens which ye chose.

And I will cause those oppressing thee to eat their own flesh, and they shall drink their blood to the full as new wine: and all flesh shall know that I am Jehovah saving thee, and redeeming thee, the Mighty One of Jacob.

And thou didst suck the milk of nations, and thou shalt suck the breast of kings: and thou knewest that I am Jehovah, saving thee and redeeming thee, the Mighty One of Jacob.
