'East Wind' in the Bible

Ephraim is enjoying wind, And is pursuing an east wind, All the day lying and spoiling he multiplieth, And a covenant with Asshur they make, And oil to Egypt is carried.

Though he among brethren produceth fruit, Come in doth an east wind, a wind of Jehovah, From a wilderness it is coming up, And it drieth up his fountain, And become dry doth his spring, It -- it spoileth a treasure -- every desirable vessel.
