It’s not good for you to brag. Don’t you know that a little yeast spreads through the whole batch of dough? Remove the old yeast ⌊of sin⌋ so that you may be a new batch of dough, since you don’t actually have the yeast ⌊of sin⌋.
Christ, our Passover lamb, has been sacrificed. So we must not celebrate our festival with the old yeast ⌊of sin⌋ or with the yeast of vice and wickedness. Instead, we must celebrate it with the bread of purity and truth that has no yeast.
