When he brought me back to the temple's entrance, I noticed that water was flowing toward the east from under the temple's threshold (the temple faced east). The water was going out from under the temple's facade toward the south, south of the altar.
References for Ezekiel 47:1
He led me out through the North Gate and around the outside to the outer East Gate, where the water flowed out under the facade on the south side.
With the line in his hand, the man went out toward the east. When he measured off fifteen hundred feet, he made me cross the water; it was ankle-deep.
He measured off another fifteen hundred feet and made me cross the water; it was knee-deep. He measured off another fifteen hundred feet and made me cross the water, and it was waist-high.
When he measured off another fifteen hundred feet, it had become a river that I couldn't cross. The water was high, deep enough for swimming but too high to cross.
He said to me, "Human one, do you see?" Then he led me back to the edge of the river.
When I went back, I saw very many trees on both banks of the river.
He said to me, "These waters go out to the eastern region, flow down the steep slopes, and go into the Dead Sea. When the flowing waters enter the sea, its water becomes fresh.
References for Ezekiel 47:8
Wherever the river flows, every living thing that moves will thrive. There will be great schools of fish, because when these waters enter the sea, it will be fresh. Wherever the river flows, everything will live.
People will stand fishing beside it, from En-gedi to En-eglayim, and it will become a place for spreading nets. It will be like the Mediterranean Sea, having all kinds of fish in it.
References for Ezekiel 47:10
Its marshes and swamps won't be made fresh (they are left for salt),
but on both banks of the river will grow up all kinds of fruit-bearing trees. Their leaves won't wither, and their fruitfulness won't wane. They will produce fruit in every month, because their water comes from the sanctuary. Their fruit will be for eating, their leaves for healing."
