'East Wind' in the Bible

Behold, seven heads of grain, thin and blasted with the east wind, sprung up after them.

and behold, seven heads of grain, withered, thin, and blasted with the east wind, sprung up after them.

The seven thin and ugly cattle that came up after them are seven years, and also the seven empty heads of grain blasted with the east wind; they will be seven years of famine.
