The Feast of Tabernacles (Sukkot)

Sacrifices & Feasts of the Old Testament collection. Last and happiest festival of the year. The water-pouring ceremony is post-biblical but essential background for John 7 - on the last day of that feast, in the middle of that ceremony, Jesus stood up in the temple and shouted that anyone thirsty should come to Him.

The Happiest Week of the Year

Remembering Homelessness in the Middle of Prosperity

By living in these structures as they feasted on the harvest, the Israelites were to teach their descendants, and to remind themselves, that the blessings of redemption and bountiful provision they enjoyed were gracious gifts from their loving King, gifts that called for an appropriate response of wholehearted dependence, obedience and worship.

The Water-Pouring Ceremony - Later Development, Essential for John 7

Not in the Torah. Morales gives the fullest description:

the high priest would take a golden pitcher and draw water from the pool of Siloam; then, followed by a procession of priests, musicians and pilgrims, he would enter the temple through the Water Gate and approach the altar. He, along with the priestly host, would circle around the altar once each of the first six days of the feast and seven times on the last and seventh day, accompanied by the singing of the Hallel (Pss 113-118). After three blasts from the shofar, he would ascend the steps of the altar and pour out the water as a libation into a silver basin while another priest poured out wine simultaneously into another, both basins having snouts so that the water and wine flowed down the altar.

New Testament Fulfilment - John 7:37-39

It was then, with the ritual of water still fresh in the minds of the people, that a man from Nazareth stood up from a visible and prominent place and cried aloud… Simply, yet profoundly, put, Jesus was saying: 'This feast is all about me! The water that flowed from the rock in the wilderness symbolized me! The sacrifice on the altar is about me! The water in the golden pitcher points to me!… No longer do you need to celebrate the feast. Celebrate me!'

A Punctuation Problem

Genuine exegetical dispute. Greek is unpunctuated so two readings possible.

The Cross as the Source

In John's record, Jesus the Messiah becomes the thirsty one under God's covenant curse, so that to those who are thirsty he may hand over his thirst-quenching Spirit (Jn. 19:30). Again, John alone notes that when one of the soldiers pierced Christ's side both blood and water flowed from it (Jn. 19:34; cf. 1 Jn. 5:6-8). Christ's death is to be seen both as a sacrifice for sins and as the means by which the water of new life in the Spirit flows to us.

Should Christians Keep It Then?
