1 Corinthians 5:8

"Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel."

"Thou shalt eat no leavened bread with it; seven days shalt thou eat unleavened bread therewith, even the bread of affliction; for thou camest forth out of the land of Egypt in haste: that thou mayest remember the day when thou camest forth out of the land of Egypt all the days of thy life."

"In the mean time, when there were gathered together an innumerable multitude of people, insomuch that they trode one upon another, he began to say unto his disciples first of all, Beware ye of the leaven of the Pharisees, which is hypocrisy."

"And they reasoned among themselves, saying, It is because we have no bread."

"Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees."

"Grace be with all them that love our Lord Jesus Christ in sincerity. Amen. «To the Ephesians written from Rome, by Tychicus.»"

"Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile!"

"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."

"That he no longer should live the rest of his time in the flesh to the lusts of men, but to the will of God."
