Behold, waters were issuing from below the threshold of the House towards the east, for the House faced eastwards. And He said, These waters are issuing out to the boundary towards the east; and they go down over the plain and come to the sea. Having been brought into the sea, the waters will be healed. And it will happen that every living creature^a that creeps, even to everything to which the water of the rivers comes, will live. And beside the river there will rise up upon its bank, on this side and on that, every tree for food. Its leaf^b will not wither, and its fruit will not fail; it is reborn monthly, for these its waters flow out from the Sanctuary, and its fruits will be for food and its leaf for medicine. Ezek 47:1, 8, 9, 12.

Here the Lord is meant by 'the east' and also by 'the Sanctuary from which waters and rivers flowed forth'. Similarly in John,

He showed me a pure river of the water of life, bright as crystal,flowing from the throne of God and of the Lamb. In the middle of its street, and of the river, on this side and on that, was the tree of life bearing twelve fruits, yielding its fruit each month; and the leaf of the tree was for the healing of the nations. Rev 22:1, 2.
