kjv@Matthew:16:21@ From that time forth began [Jesus] to shew unto his disciples, how that he must go unto [Jerusalem], and suffer many things of the elders and [Chief] priests and [Scribes], and be killed, and be raised again the third [Day].
kjv@Matthew:16:22@ Then [Peter] took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee.
kjv@Matthew:16:23@ But he turned, and said unto [Peter], Get thee behind me, Satan: thou art an [Offence] unto me: for thou savourest not the things that be of [God], but those that be of men.
kjv@Matthew:16:24@ Then said [Jesus] unto his disciples, If any [Man] will come after me, let him deny himself, and take up his [Cross], and follow me.
kjv@Matthew:16:25@ For whosoever will save his [Life] shall lose it: and whosoever will lose his [Life] for my sake shall find it.
kjv@Matthew:16:26@ For what is a [Man] profited, if he shall gain the whole world, and lose his own soul? or what shall a [Man] give in exchange for his soul?
The comment about the leaven of the Pharisees is just as much a observation of what is currently transpiring against Him as it is a doctrinal fidelity teaching. Jesus sees what is developing and the rage mounting against Him so He checks to see how far along the Disciples hearts are in the revelation process. They are currently far enough to know that He is Christ but, not so far as to know what Christ must suffer for them in the very near future. Until they grasp this further more complete revelation they will not grasp their own future pathway - the baring of their own cross for Him in His absence up until His return.
