Get rid of the old “yeast” by removing this wicked person from among you. Then you will be like a fresh batch of dough made without yeast, which is what you really are. Christ, our Passover Lamb, has been sacrificed for us.
So get rid of this "yeast." Our true identity is flat and plain, not puffed up with the wrong kind of ingredient. The Messiah, our Passover Lamb, has already been sacrificed for the Passover meal, and we are the Unraised Bread part of the Feast.
