The Lamb of God
Mark 14:22 And as they did eat, Jesus took bread, and blessed, and brake it, and gave to them, and said, Take, eat: this is my body.
Jesus was using the bread as symbolism for His body, he blessed the bread, broke it and said, take, eat: this is my body.
1 Cor 11:23 For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread:
1 Cor 11:24 And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me.
We are to do this in remembrance of his broken body. His bones would be pulled out of their sockets and his flesh would be broken and torn for our sins. Yet not a bone would be broken, to fulfill prophecy.
On the cross
John 19:33 But when they came to Jesus, and saw that he was dead already, they brake not his legs:
John 19:34 But one of the soldiers with a spear pierced his side, and forthwith came there out blood and water.
John 19:35 And he that saw it bare record, and his record is true: and he knoweth that he saith true, that ye might believe.
John 19:36 For these things were done, that the scripture should be fulfilled, A bone of him shall not be broken.
The reference to not breaking the bone, concerned the Passover Lamb.
Exo 12:46 In one house shall it be eaten; thou shalt not carry forth ought of the flesh abroad out of the house; neither shall ye break a bone thereof.
Jesus is the Lamb of God.
John 1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
Rev 5:13 And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.
