Kutoka 12 : 19 Exodus chapter 12 verse 19

Muda wa siku saba isionekane chachu katika nyumba zenu kabisa; kwa kuwa mtu ye yote atakayekula hiyo iliyotiwa chachu, nafsi hiyo atakatiliwa mbali na mkutano wa Israeli, akiwa mwenye kukaa hali ya ugeni, au akiwa mtu aliyezaliwa katika nchi.
soma Mlango wa 12

Seven days shall there be no yeast found in your houses, for whoever eats that which is leavened, that soul shall be cut off from the congregation of Israel, whether he be a foreigner, or one who is born in the land.
