Speak unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for a house:
All Commentaries on Exodus 12:3 Go To Exodus 12
Jerome
AD 420
“The lamb,” the Lord says, “must be without blemish. You may take it from either the sheep or the goats.” In another place of Holy Writ, it is prescribed that if anyone is unable to keep the Passover in the first month, he is to do so in the second. According to the regulation above, anyone who is unable to sacrifice a lamb may substitute a kid. In the house of the church, moreover, Christ is offered in a twofold manner: if we are just, we eat of the flesh of the lamb; if we are sinners and do penance, for us a goat is slain. This does not mean that Christ is from the goats that stand, as he has taught, on his left hand, but that Christ becomes a lamb or a goat in conformity with individual and personal merit.
