John 18:9

That the saying might be fulfilled which he spake, Of them which thou gavest me have I lost none--The reference is to such sayings as Joh 6:39; Joh 17:12; showing how conscious the Evangelist was, that in reporting his Lord's former sayings, he was giving them not in substance merely, but in form also. Observe, also, how the preservation of the disciples on this occasion is viewed as part that deeper preservation undoubtedly intended in the saying quoted.

Hitherto this evangelist has recorded little of the history of Christ, only so far as was requisite to introduce his discourses; but now that the time drew nigh that Jesus must die he is very particular in relating the circumstances of his sufferings, and some which the others had omitted, especially his sayings. So far were his followers from being ashamed of his cross, or endeavouring to conceal it, that this was what, both by word and writing, they were most industrious to proclaim, and gloried in it. This chapter relates, I. How Christ was arrested in the garden and surrendered himself a prisoner (Joh 18:1-12). II. How he was abused in the high priest's court, and how Peter, in the meantime, denied him (Joh 18:13-27). III. How he was prosecuted before Pilate, and examined by him, and put in election with Barabbas for the favour of the people, and lost it (Joh 18:28-40).

18:9 I did not lose a single one: Jesus continued to be a good shepherd, offering his life for the sheep and protecting them from the wolves (10:11-15). From the beginning, however, Judas Iscariot had not been a true disciple of Jesus (17:12).
