There is nothing very special in connexion with the unnamed feast; and the Passover of vi. 4 is mentioned only by the way. But in the account of the Feast of Tabernacles there is a precise touch in vii. 37, ‘on the last day, the great day of the feast.’ This shows accurate knowledge, because the last day was kept as a sabbath with an ‘holy convocation’ (Lev. xxiii. 36). Whether, as many have supposed, our Lord’s words on this day (‘If any man thirst, let him come unto me, and drink’) were suggested by the libations of water from Siloam poured out during the feast, is a question of association that is hardly capable of proof, but may be true[47]. There is nice accuracy in the picture presented by xi. 55-7:— ‘Now the passover of the Jews was at hand: and many went up to Jerusalem out of the country before the passover, to purify themselves. They sought therefore for Jesus, and spake one with another, as they stood in the temple, What think ye? That he will not come to the feast? Now the chief priests and the Pharisees had given commandment, that, if any man knew where he was, he should shew it, that they might take him.’ The strictest ritualistic purity was required of those who took part in the feast. ‘Every man,’ said R. Isaac, ‘is bound to purify himself for the feast’ (Lightfoot, _Hor. Hebr._ ad loc.). The purifying might take quite seven days, and during this time the pilgrims to the feast would be standing about and often conversing among themselves, and the rumours of the day would circulate freely among them. There are several pointed allusions in the Gospel to the laws of Levitical purity. The mention of the water-jars at the miracle of Cana is one; the dispute of John’s disciples with a Jew about purifying is perhaps another; we have just had a third; and a fourth is in xviii. 28, where the Sanhedrists are prevented from entering the _praetorium_, in order not to incur defilement, and so be prevented from eating the passover[48]. These allusions are really, if we think of it, very striking. They fit into the narrative with perfect ease and appropriateness; and they are admirably natural if the author of the Gospel was really St. John, a Christian brought up as a Jew, and even as it would seem in some way personally connected with the priesthood, who had been himself in the company of Jesus, had himself held intercourse with disciples of the Baptist, and himself moved about among the crowds and heard their comments. It is a wholly different thing if we are to suppose that all these touches were thrown in by a Christian of the third generation, who could only arrive at them by study and imagination. Chwolson says expressly: ‘After the destruction of the Temple all the regulations about cleanness and uncleanness, which were closely connected with the sacrificial system, fell into disuse[49].’ The last instance that I will notice is xix. 31, which is full of the same truth of detail.
