6 Jesus said to them, “Take heed and beware of the yeast of the Pharisees and Sadducees.” 7 They reasoned among themselves, saying, “We brought no bread.” 8 Jesus, perceiving it, said, “Why do you reason among yourselves, you of little faith, ‘because you have brought no bread?’ 9 Don’t you yet perceive, neither remember the five loaves for the five thousand, and how many baskets you took up? 10 Nor the seven loaves for the four thousand, and how many baskets you took up? 11 How is it that you don’t perceive that I didn’t speak to you concerning bread? But beware of the yeast of the Pharisees and Sadducees.” 12 Then they understood that he didn’t tell them to beware of the yeast of bread, but of the teaching of the Pharisees and Sadducees.

Commentary on Matthew 16:5-12
(Read Matthew 16:5-12)
Christ speaks of spiritual things under a similitude, and the disciples misunderstand him of carnal things. He took it ill that they should think him as thoughtful about bread as they were; that they should be so little acquainted with his way of preaching. Then understood they what he meant. Christ teaches by the Spirit of wisdom in the heart, opening the understanding to the Spirit of revelation in the word.
