'Strength' in the Bible

because that he had been often bound with fetters and chains, and the chains had been rent asunder by him, and the fetters broken in pieces: and no man had strength to tame him.

and thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength.

and to love him with all the heart, and with all the understanding, and with all the strength, and to love his neighbor as himself, is much more than all whole burnt-offerings and sacrifices.
