'Soul' in the Bible

and thou shalt love the Lord thy God out of all thy heart, and out of thy soul, and out of all thine understanding, and out of all thy strength -- this is the first command;

and to love Him out of all the heart, and out of all the understanding, and out of all the soul, and out of all the strength, and to love one's neighbour as one's self, is more than all the whole burnt-offerings and the sacrifices.'

and he saith to them, 'Exceeding sorrowful is my soul -- to death; remain here, and watch.'
