1 Corinthians 10:4
1 For I do not want you to be unaware, brothers and sisters, that our fathers were all under the cloud and all passed through the sea, 2 and all were baptized into Moses in the cloud and in the sea, 3 and all ate the same spiritual food, 4 and all drank the same spiritual drink. For they were all drinking from the spiritual rock that followed them, and the rock was Christ. 5 But God was not pleased with most of them, for they were cut down in the wilderness. 6 These things happened as examples for us, so that we will not crave evil things as they did.
Tosefta Sukkah 3Tosefta
And also : By the river, upon the bank thereof, on this side and on that side, shall grow every tree for meat, whose leaf shall not wither, neither shall the fruit thereof fail ; it shall bring forth first-fruits every month, because the waters thereof issue out of the sanctuary ; and the fruit thereof shall be for meat, and the leaf thereof for healing intimating that all "the waters of creation" will come forth as from the mouth of this flask. So the well, which was with Israel in the wilderness, was like a rock of the size of a k'bara, and was oozing out and rising as from the mouth of this flask, travelling with them up the mountains and going down with them to the valleys. Wherever Israel encamped it encamped opposite them before the door of the Tabernacle. The princes of Israel with their slaves surrounded it, and said over it this song, Spring up, O well, sing ye unto it. Then the waters bubbled forth, and rose on high like a pillar; and every one drew out the staff of his tribe and family, as it is said, The well which the princes digged, Which the nobles of the people delved, With the sceptre and with their staves. And from Mattanah to Nahaliel ; and from Nahaliel to Bamoth ; and from Bamoth to the valley, etc. going round every camp of the Lord, and watering all Jeshimon ; and it made mighty streams, as it is said, And streams overflowed. 3 And they were sitting in skiffs, going from place to place, as it is written, They ran in the dry places like a river. If Israel went up on the right, it would come down on the right ; if on the left, it would come down on the left. The waters which emptied themselves from it became a great river, pouring themselves into the Mediterranean, and bringing thence all the precious things of the world, as it is said, These forty years the Lord thy God hath been with thee ; thou hast lacked nothing.
Notes and References
"... Paul cites two characteristic practices of primitive Christianity to interpret the lsrael of the exodus as the Israel of faith: 'All passed through the sea, and all were baptized into Moses in the cloud and in the sea. And they all ate the same spiritual food, and all drank the same spiritual drink' (1 Corinthians 10:2-3). The passage through the sea (Exodus 14:16) is the type fulfilled by baptism, and the pillar of cloud and fire that guided the Israelites (Exodus 13:21-22; 14:19-24) is now the Spirit of God, into which every believer is also baptized. Likewise, the miraculous provision of food and drink in the wilderness (Exodus 16-17) is associated with the 'spiritual' provision of Eucharist. Because the 'rock' from which the water came is referred to more than once in the cycle of the exodus from Egypt (see Numbers 20-21), Paul joins rabbinic tradition in imagining that the rock followed the Israelites, and he sees in Christ the fulfillment of the type ..."
