11 Haven't you realized yet that bread isn't the problem? The problem is yeast, Pharisee-Sadducee yeast." 12 Then they got it: that he wasn't concerned about eating, but teaching - the Pharisee-Sadducee kind of teaching.

Matthew Henry's Commentary on Matthew 16:11-12

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.
