John 19:37 & Zechariah 12:10
John 19:34 (NIV) Instead, one of the soldiers pierced Jesus' side with a spear, bringing a sudden flow of blood and water. 35 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. 36 These things happened so that the scripture would be fulfilled: "Not one of his bones will be broken," {[36] Exodus 12:46; Num. 9:12; Psalm 34:20} 37 and, as another scripture says, "They will look on the one they have pierced." {[37] Zech. 12:10}
Zech 12:10 (NIV) And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and supplication. They will look on me, the one they have piercedÉ
