When they were filled, he said to his disciples, "Gather up the broken pieces which are left over, that nothing be lost."

 Jesus said we must drink his blood. In Jewish thought the blood stands for the life. It is easy to understand why. As the blood flows from a wound, life ebbs away; and to the Jew, the blood belonged to God. That is why to this day a true Jew will never eat any meat which has not been completely drained of blood. "Only you shall not eat flesh with its life, that is, its blood" ( Genesis 9:4). "Only you shall not eat its blood" ( Deuteronomy 15:23). Now see what Jesus is saying--"You must drink my blood--you must take my life into the very centre of your being--and that life of mine is the life which belongs to God." When Jesus said we must drink his blood he meant that we must take his life into the very core of our hearts.
