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
Bede
AD 735
It was commanded that the paschal lamb, by whose immolation the people of Israel were freed from slavery in Egypt, should be selected five days before the [feast of] Passover, that is, on the tenth [day of the lunar] month, and immolated on the fourteenth [day of the lunar] month at sundown. This signified the one who was going to redeem us by his blood, since five days before the [feast of] Passover (that is, today), accompanied by the great joy and praise of people going ahead and following, he came into God’s temple, and he was there teaching daily. At last, after five days, having observed up to that point the sacraments of the old Passover, he brought them to perfect fulfillment, and he handed over the new sacraments to his disciples to be observed henceforth.[Then], having gone out to the Mt. of Olives, he was seized by the Jews and crucified [the next] morning. He redeemed us from the sway of the devil on that very day when the ancient people of the Hebrews cast aside the yoke of slavery under the Egyptians by the immolation of the lamb.
