Mark 8:15 - Then He charged them, saying, "Take heed, beware of the leaven of the Pharisees and the leaven of Herod." [NKJV]
In The Bible, "leaven" is used both literally (the yeast that makes bread rise) and figuratively (a relatively small force or amount that nonetheless makes a major impact). As used by Jesus in Mark 8:15, "leaven" refers to a "corrupting influence."

Philip was the son of King Herod the Great and brother of Antipas, who took the name Herod Antipas but is referred to in the Bible simply as Herod. On the death of Herod the Great, Antipas inherited Galilee, while Philip received the territory east of Jordan.
A common interpretation is that the meal is the world and the leaven is the gospel which will be preached throughout the world until everyone becomes saved. However leaven is always a type of sin, evil, false doctrine in the Bible. For example Jesus warned against the leaven of the Pharisees and Sadducees (Matthew 16:6, Matthew 16:12) and the leaven of Herod (Mark 8:15). In 1Corinthians 5:6-8 leaven is defined as malice and evil. So in this parable Jesus warns against the permeating power of evil working in the kingdom of heaven.
