'East Wind' in the Bible

Ephraim feeds on wind, and chases the east wind. He continually multiplies lies and desolation. They make a covenant with Assyria, and oil is carried into Egypt.

Though he is fruitful among his brothers, an east wind will come, the breath of Yahweh coming up from the wilderness; and his spring will become dry, and his fountain will be dried up. He will plunder the storehouse of treasure.
