John 19:35

And he that saw it bare record--hath borne witness. and his witness is true, and he knoweth that he saith true, that ye might believe--This solemn way of referring to his own testimony in this matter has no reference to what he says in his Epistle about Christ's "coming by water and blood" (see on Jo1 5:6), but is intended to call attention both to the fulfilment of Scripture in these particulars, and to the undeniable evidence he was thus furnishing of the reality of Christ's death, and consequently of His resurrection; perhaps also to meet the growing tendency, in the Asiatic churches, to deny the reality of our Lord's body, or that "Jesus Christ is come in the flesh" (Jo1 4:1-3).

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!

19:35 John was at the foot of the cross (19:26). He was not simply a collector of traditions about Jesus, but an eyewitness giving an accurate account of the events of Jesus’ life (cp. 21:24). This same confidence can be seen in the opening of John’s first letter (1 Jn 1:1-4).
