Matthew

In the mean time, when there were gathered together an innumerable multitude of people, insomuch that they trode one upon another, he began to say unto his disciples first of all, Beware ye of the leaven of the Pharisees, which is hypocrisy.

Take heed that ye do not your alms before men, to be seen of them: otherwise ye have no reward of your Father which is in heaven.

And he charged them, saying, Take heed, beware of the leaven of the Pharisees, and of the leaven of Herod.

A little leaven leaveneth the whole lump.

Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.
