And they shall take of the blood, and put it on the two side-posts and on the lintel, upon the houses wherein they shall eat it. And they shall eat the flesh in that night, roast with fire, and unleavened bread; with bitter herbs they shall eat it. Eat not of it raw, nor sodden at all with water, but roast with fire; its head with its legs and with the inwards thereof. And ye shall let nothing of it remain until the morning; but that which remaineth of it until the morning ye shall burn with fire. And thus shall ye eat it: with your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste—it is the LORD’s passover.

And thou shalt sacrifice the passover-offering unto the LORD thy God, of the flock and the herd, in the place which the LORD shall choose to cause His name to dwell there.

וזבחת פסח לה' אלהיך צאן THOU SHALT THEREFORE SACRIFICE THE PASSOVER UNTO THE LORD THY GOD OF SHEEP, as it is said of the Passover offering, (Exodus 12:5) “Ye shall take it from the sheep or from the goats”, — ובקר AND OXEN thou shalt slaughter as the חגיגה (the festival offering sacrificed on the fourteenth of Nisan in addition to the Passover offering); for if they have counted themselves (formed themselves) into too large a company for the Passover offering (so that one lamb will not suffice for them) they bring together with it a festival offering and this is eaten first, in order that it (the Passover sacrifice) can be eaten in satiety (i.e. after the appetite is satisfied; cf. Pesachim 69b, 70a). — And besides this our Rabbis derived many Halachic matters from this verse (cf. Sifrei Devarim 129; Berakhot 9a).
