1 Cor 5:6-8
6d Your boasting is not appropriate. Do you not know that a little yeast* leavens all the dough? 7* Clear out the old yeast, so that you may become a fresh batch of dough, inasmuch as you are unleavened. For our paschal lamb, Christ, has been sacrificed.e 8Therefore, let us celebrate the feast, not with the old yeast, the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.f
Mk 4:21-25
Parable of the Lamp. 21e He said to them, “Is a lamp brought in to be placed under a bushel basket or under a bed, and not to be placed on a lampstand?f 22For there is nothing hidden except to be made visible; nothing is secret except to come to light.g 23Anyone who has ears to hear ought to hear.” 24He also told them, “Take care what you hear. The measure with which you measure will be measured out to you, and still more will be given to you.h 25To the one who has, more will be given; from the one who has not, even what he has will be taken away.”i
