who came not according to the law of a fleshly command, but according to the power of an endless life,

By faith also Sarah herself did receive power to conceive seed, and she bare after the time of life, seeing she did judge Him faithful who did promise;

quenched the power of fire, escaped the mouth of the sword, were made powerful out of infirmities, became strong in battle, caused to give way camps of the aliens.
