Matthew 16:10-12 King James Version (KJV)
10 Neither the seven loaves of the four thousand, and how many baskets ye took up?
11 How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees?
12 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.
Matthew 16:10-12 New International Version (NIV)
10 Or the seven loaves for the four thousand, and how many basketfuls you gathered? 11 How is it you don’t understand that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees.” 12 Then they understood that he was not telling them to guard against the yeast used in bread, but against the teaching of the Pharisees and Sadducees.
