Ezekiel 47:8

Then he cried out to Yahweh, and Yahweh showed him a tree; and he threw it into the waters, and the waters became sweet. There He set for them a statute and a judgment, and there He tested them.

And it will be in that day, That the mountains will drip with sweet wine, And the hills will flow with milk, And all the brooks of Judah will flow with water; And a spring will go out from the house of Yahweh To water the valley of Shittim.

And in that day His feet will stand on the Mount of Olives, which is in front of Jerusalem on the east; and the Mount of Olives will be split in its middle from east to west by a very large valley so that half of the mountain will move toward the north and the other half toward the south.

And it will be in that day, that living waters will flow out of Jerusalem, half of them toward the eastern sea and the other half toward the western sea; it will be in summer as well as in winter.
