“And hee charged them, saying, Take heed, beware of the leauen of the Pharisees, and of the leauen of Herode.”
1611 King James Version (KJV)
8:15 Beware of the leaven of the Pharisees and of Herod, or of the Sadducees; two opposite extremes.
Mr 8:15 Leaven of Herod. Matthew says "Sadducees" (Mt 16:6) instead of "Herod". Herod was a Sadducee, and the Sadducees generally were his supporters.
