'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 the LORD 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.
