'East Wind' in the Bible

Ephraim feedeth on wind, and followeth after the east wind: he continually multiplieth lies and desolation; and they make a covenant with Assyria, and oil is carried into Egypt.

Though he be fruitful among his brethren, an east wind shall come, the breath of Jehovah coming up from the wilderness; and his spring shall become dry, and his fountain shall be dried up: he shall make spoil of the treasure of all goodly vessels.
