'Understanding' in the Bible

and he saith to them, 'So also ye are without understanding! Do ye not perceive that nothing from without entering into the man is able to defile him?

but they were not understanding the saying, and they were afraid to question him.

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 Jesus, having seen him that he answered with understanding, said to him, 'Thou art not far from the reign of God;' and no one any more durst question him.
