Jn 1:29, 36, 19:33, 36
God commanded not to break the bones of the Passover lamb. (Ex 12:46)
Ex 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 Christ, the Passover Lamb. (John 1:29,36)
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. 36 And looking upon Jesus as he walked, he saith, Behold the Lamb of God!
Jesus died for us as prophesied about the Passover lamb in the Old Testament, and his legs were not broken. (John 19:33,36)
John 19:33 But when they came to Jesus, and saw that he was dead already, they brake not his legs: 36 For these things were done, that the scripture should be fulfilled, A bone of him shall not be broken.
