'East Wind' in the Bible

Ephraim fed upon the wind, and he pursued the east wind: all the day he multiplied falsehood and destruction; and they will cut out a covenant with Assur, and oil will be brought to Egypt

If he shall bear fruit in the midst of his brethren, the east wind shall come, the wind of Jehovah came up from the desert, and his fountain shall be dried up, and he shall lay waste his place of fountains: he shall plunder the treasure of all vessels of desire.
