John 19:34-37

But one of the soldiers pierced His side with a spear, and immediately blood and water came out. And he who has seen has testified, and his testimony is true; and he knows that he is telling the truth, so that you also may believe. For these things came to pass to fulfill the Scripture, “NOT A BONE OF HIM SHALL BE BROKEN.” And again another Scripture says, “THEY SHALL LOOK ON HIM WHOM THEY PIERCED.”
