1CO 5:7

7 So, [just like we Jews] expel the old yeast [from our houses during the Passover celebration] in order that we may have a fresh batch of dough without yeast in it [MET], [you must expel such evil people from your congregation]. Do [that so that you can truly be holy people], as [I know that] you really are. Remember that Christ was sacrificed {sacrificed himself} [so that God could spare us from being punished for our sins, just like the Jews sacrificed lambs during] the [first] Passover celebration [so that God would spare their firstborn sons from being killed].
