Matthew - 16:12 Meaning
“Then understood they how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.”
King James Version (KJV)
Matthew Henry's Concise Commentary
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.
“And thou shalt bring the meat offering that is made of these things unto the LORD: and when it is presented unto the priest, he shall bring it unto the altar.”
