'Mighty One' in the Bible

Gird thy sword upon thy thigh, O mighty one, -- Tis thine honour and thy majesty;

For lo! they have lain in wait for my life, Mighty ones stir up strife against me, Without transgression of mine, and without sin of mine, O Yahweh;

Then spakest thou in vision of thy men of lovingkindness, and saidst - I have laid help upon a mighty one, I have exalted one chosen from among the people;

Until I find a place for Yahweh, habitations for the Mighty One of Jacob.
