'Level' in the Bible

The way of the just is uprightness. You who are upright make the path of the righteous level.

The voice of one who calls out, "Prepare the way of Yahweh in the wilderness! Make a level highway in the desert for our God.

Every valley shall be exalted, and every mountain and hill shall be made low. The uneven shall be made level, and the rough places a plain.
