1 Corinthians 5:6-8

Complete Jewish Bible

⁶ Your boasting is not good. Don’t you know the saying, “It takes only a little hametz to leaven a whole batch of dough?” ⁷ Get rid of the old hametz, so that you can be a new batch of dough, because in reality you are unleavened. For our Pesach lamb, the Messiah, has been sacrificed. ⁸ So let us celebrate the Seder not with leftover hametz, the hametz of wickedness and evil, but with the matzah of purity and truth.
