There are probably two, both referring to later additions to the ceremonies. One is in John 7:37. We learn from the Talmud that on each of the seven days (and according to one Rabbi on the eighth also) a priest went down to Siloam and drear water in a golden pitcher, which he brought back amid the blare of trumpets to the altar, and poured into a silver basin while the joyous worshippers chanted the Great Hallel' (Psa. 113-118.), and thrice waved their palm branches as they sang. We may venture to suppose that this had been done for the last time; that the shout of song had scarcely died away when a stir in the crowd was seen, and a Galilean peasant stood forth, and there, before the priests with their empty vessels, and the hushed multitude, lifted up His voice, so as to be heard by all, and cried, saying: If any man thirst, let him come unto He, and drink.' What increased force is given to the extraordinary self-assertion of such words, if we picture this as the occasion of their utterance! Leviticus gives no preeminence to any one day, but John's expression, that great day of the feast,' may well have been warranted by later developments.
The other allusion is less certain, though it is probable. It is found in the saying at John 8:12: I am the Light of the world,' etc. The Talmud gives a detailed account of the illuminations accompanying the feast. Four great golden lamps were set up in the court, each tended by four young priests. There was not a court in Jerusalem that was not lit up by the lights of the water-drawing.' Bands of grave men with flashing torches danced before the people, while Levites accompanied them with harps, psalteries, cymbals, and numberless musical instruments,' and another band of Levites standing on the fifteen steps which led to the women's court, chanted the fifteen so-called songs of degrees,' and yet others marched through the courts blowing their trumpets as they went. It must have been a wild scene, dangerously approximating to the excitement of heathen nocturnal festivals, and our Lord may well have sought to divert the spectators to higher thoughts. But the existence of the allusion is doubtful.
