What Is the Eucharist, the Lamb of God?

The beging of the wek is marked by the lamb coming into their home. And so this was an opportunity for the men of the people of israel to be brought into the covenant via circumcision. They are circumcised, they ar healing, and by the end of the week, when they have the roast lamb and they sacrifice it and what not, they will be healed enough to move in flight. Now, why would they have to be circumcised? Well, because it says, the very end of chapter 12 ad says, if unless you're brought into the Covenant via circumcision, you actually cannot,. you may not partake of the sacrificial lamb.
