John 19:37

And again another scripture saith, They shall look on him whom they pierced--The quotation is from Zac 12:10; not taken as usual from the Septuagint (the current Greek version), which here is all wrong, but direct from the Hebrew. And there is a remarkable nicety in the choice of the words employed both by the prophet and the Evangelist for "piercing." The word in Zechariah means to thrust through with spear, javelin, sword, or any such weapon. In that sense it is used in all the ten places, besides this, where it is found. How suitable this was to express the action of the Roman soldier, is manifest; and our Evangelist uses the exactly corresponding word, which the Septuagint certainly does not. Very different is the other word for "pierce" in Psa 22:16, "They pierced my hands and my feet." The word there used is one signifying to bore as with an awl or hammer. How striking are these small niceties!

Though in the history hitherto this evangelist seems industriously to have declined the recording of such passages as had been related by the other evangelists, yet, when he comes to the sufferings and death of Christ, instead of passing them over, as one ashamed of his Master's chain and cross, and looking upon them as the blemishes of his story, he repeats what had been before related, with considerable enlargements, as one that desired to know nothing but Christ and him crucified, to glory in nothing save in the cross of Christ. In the story of this chapter we have, I. he remainder of Christ's trial before Pilate, which was tumultuous and confused (Joh 19:1-15). II. Sentence given, and execution done upon it (Joh 19:16-18). III. The title over his head (Joh 19:19-22). IV. The parting of his garment (Joh 19:23, Joh 19:24). V. The care he took of his mother (Joh 19:25-27). VI. The giving him vinegar to drink (Joh 19:28, Joh 19:29). VII. His dying word (Joh 19:30). VIII. The piercing of his side (Joh 19:31-37). IX. The burial of his body (Joh 19:38-42). O that in meditating on these things we may experimentally know the power of Christ's death, and the fellowship of his sufferings!

19:37 “They will look on the one they pierced”: Zechariah 12:10 describes how Israel would look on a prophet or the Messiah and lament their own fatal lack of faith.
