'Strength' in the Bible

And wherever it takes him, it puts him down violently, streaming at the lips and twisted with pain; and his strength goes from him; and I made a request to your disciples to send it out, and they were not able.

And you are to have love for the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.

And to have love for him with all the heart, and with all the mind, and with all the strength, and to have the same love for his neighbour as for himself, is much more than all forms of offerings.
