Ezekiel 47:8 הַקַּדְמוֹנָ֔ה <the> eastern

And he said to me, “This water flows out to the eastern region and goes down into the Arabah. When it empties into the Dead Sea, the water there becomes fresh.

Here: This adjective appears only here in the Bible. It comes from qedem, 'front/east', because the east is the direction a person faces toward the sunrise. In Ezekiel the east matters: God's glory left the temple eastward (11:23) and came back from the east (43:2). Now life flows out the same way.
