John 19:34-37

34But one of the soldiers pierced his side with a spear, and at once blood and water came out.

35He who saw this has testified so that you also may believe. His testimony is true, and he knows he is telling the truth.

36For these things happened so that the Scripture would be fulfilled: Not one of his bones will be broken.

37Also, another Scripture says: They will look at the one they pierced.
