Exodus 12:6 WEB

⁴  and if the household be too little for a lamb, then he and his neighbor next to his house shall take one according to the number of the souls; according to what everyone can eat you shall make your count for the lamb.

⁵  Your lamb shall be without blemish, a male a year old. You shall take it from the sheep, or from the goats:

⁶  and you shall keep it until the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall kill it at evening.

⁷  They shall take some of the blood, and put it on the two side-posts and on the lintel, on the houses in which they shall eat it.

⁸  They shall eat the flesh in that night, roasted with fire, and unleavened bread. They shall eat it with bitter herbs.
