'East Wind' in the Bible

Ephraim feeds on the [emptiness of the] windAnd [continually] pursues the [parching] east wind [which brings destruction];Every day he multiplies lies and violence.Further, he makes a covenant with AssyriaAnd (olive) oil is carried to Egypt [to seek alliances].

For though he flourishes among the reeds (his fellow tribes),An east wind (Assyria) will come,The breath of the Lord rising from the desert;And Ephraim’s spring will become dryAnd his fountain will be dried up.Assyria will plunder his treasury of every precious object.
