“Beware’s” – Beware of:

False Prophets

Matthew 7:15  

“Watch out for false prophets. They come to you in sheep's clothing, but inwardly they are ferocious wolves.

Men

Matthew 10:17  

“Be on your guard against men; they will hand you over to the local councils and flog you in their synagogues.

Leaven (doctrine) of Pharisees

Matthew 16:6-12  

6 “Be careful,” Jesus said to them. “Be on your guard against the yeast of the Pharisees and Sadducees.”

7 They discussed this among themselves and said, “It is because we didn't bring any bread.”

8 Aware of their discussion, Jesus asked, “You of little faith, why are you talking among yourselves about having no bread?

9 Do you still not understand? Don't you remember the five loaves for the five thousand, and how many basketfuls you gathered?

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.

Leaven (doctrine) of Herod

Mark 8:15  

“Be careful,” Jesus warned them. “Watch out for the yeast of the Pharisees and that of Herod.”
