Exodus 12:2-8

MLV(i) 2 This month will be to you* the beginning of months; it will be the first month of the year to you*.
3 Speak to all the congregation of Israel, saying, In the tenth day of this month they will take to them every man a lamb, according to their fathers' houses, a lamb for a household. 4 And if the household be too little for a lamb, then he and his neighbor next to his house will take one according to the number of the souls, according to every man's eating you* will make your* count for the lamb.
5 Your* lamb will be without blemish, a male a year old. You* will take it from the sheep, or from the goats. 6 And you* will keep it until the fourteenth day of the same month and the whole assembly of the congregation of Israel will kill it at evening.
7 And they will take of the blood and put it on the two side-posts and on the lintel upon the houses in which they will eat it. 8 And they will eat the flesh in that night, roasted with fire and unleavened bread, with bitter herbs they will eat it.
