Zechariah 14:8
6 On that day there will be no light—the sources of light in the heavens will congeal. 7 It will happen in one day—a day known to the Lord—not in the day or the night, but in the evening there will be light. 8 Moreover, on that day living waters will flow out from Jerusalem, half of them to the eastern sea and half of them to the western sea; it will happen both in summer and in winter. 9 The Lord will then be king over all the earth. In that day the Lord will be seen as one with a single name. 10 All the land will change and become like the rift valley from Geba to Rimmon, south of Jerusalem. Jerusalem will be raised up and will stay in its own place from the Benjamin Gate to the site of the First Gate and on to the Corner Gate, and from the Tower of Hananel to the royal winepresses.
1 Enoch 17:4
2 And they led me to a place of darkness, and to a mountain whose peak reached to heaven. 3 And I saw the places of the sun and moon and the treasuries of the stars and of the thunder in the utmost depths, where there was a fiery bow and arrows and their quiver, and a fiery sword and all the lightnings. 4 And they took me to the living waters, and to the fire of the west, which receives every setting of the sun. 5 And I came to a river of fire where the fire flows like water and pours into the great sea towards the west. 6 I saw the great rivers and came to the great river and to the great darkness, and went to the place where no flesh walks.
Notes and References
"... The significance of the living waters and of the fire of the west (17:4), to which Enoch is next led, is not entirely clear. The expression “living waters” is used in the Hebrew Bible to express the meaning “fresh water” (e.g. Genesis 26:19), but that is hardly what is intended here. The expression is also used in Zechariah 14:8 in a context referring to life-giving water, and it is possible that this is what is in mind in 1 Enoch, but if so, the idea is not developed ..."

"... The next section (1 Enoch 17:4-5) with its references to various kinds of waters and rivers is leas transparently the kind of thing one would expect to find in a royal tour, But rivers were not simply geographical features in the ancient Near Bast. The “living waters” of v. 4 are typologically the same as the living waters of Zechariah 14:8 which flow out of Jerusalem on the day that “Yahweh will become king over all the earth" (Zechariah 14:9). They are the means of prosperity and bounty which are associated with the ideology of kingship, divine and human ..."
