John 19:34-37

Instead, one of the soldiers pierced Jesus’ side with a spear, bringing a sudden flow of blood and water. The man who saw it has given testimony, and his testimony is true. He knows that he tells the truth, and he testifies so that you also may believe. These things happened so that the scripture would be fulfilled: “Not one of his bones will be broken,” and, as another scripture says, “They will look on the one they have pierced.”
