John 19:35 He who saw this has given evidence so that you also may be faithful. His evidence is true, and he knows he is telling the truth
John 19:36 because these things happened so that the Scripture would be fulfilled: Not one of his bones will be broken.
John 19:37 Also, another Scripture says: They will stare at the one they stabbed.
two types of evidence
John gives two types of evidence for Jesus’ crucifixion which he had just narrated. First, he testifies that he was there and he saw it. He was an eyewitness. Secondly, he testifies that what happened fulfilled Scripture.
That Jesus would go through his ordeal without having any major bones broken fulfilled the prophecy found in Psalm 34:20. The significance is that the Passover lamb was to be eaten in one place, without breaking any of its bones (Exodus 12:46; Numbers 9:12).
That Jesus would be stared at after having been stabbed by a spear fulfilled the prophecy found in Zechariah 12:10, and Psalm 22:16-17, and alluded to in Revelation 1:7.
Armed with Scripture and the testimony of own experience, we also can share with others the story of what our Savior has done.
