33But when they came to Jesus, and saw that he was dead already, they brake not his legs: 34But one of the soldiers with a spear pierced his side, and forthwith came there out blood and water. 35And he that saw it bare record, and his record is true: and he knoweth that he saith true, that ye might believe. 36For these things were done, that the scripture should be fulfilled, A bone of him shall not be broken. 37And again another scripture saith, They shall look on him whom they pierced.
Comment: The point of this passage is that something unusual occurred in Jesus' crucifixion. He had died before the other crucifixion victims. Why the unusual death? John noticed that it parallels two scriptures; one interpreting the Passover lamb in a symbolic fashion and another claiming the Messiah would be one who was pierced. The Passover lamb was not to have its bones broken but no explicit reason for that is recorded in the scriptures. Was it just a coincidence that Jesus bones were not broken and that he was being crucified at the same time the Paschal lambs were being slaughtered or was it that an Old Testament symbol was being fulfilled in the death of the Messiah? Also why would the scripture say the Jews would look upon him whom they pierced? For that to be fulfilled, the Messiah would need to be pierced somehow and the Jews would need to see the one pierced. So here we have those requirements being fulfilled. Given that Jesus' death fulfilled scripture, it would stand to reason the scriptures requiring a resurrection would be fulfilled as well (e.g. Psalm 16:10).
