From the Old Testament there is reference to “the east wind” (Gen.41:23, Jer. 18:17, etc). I also came upon it in the Book of Mormon, in Mosiah. What is meant by the “east wind”. Where does this expression come from?
The East Wind is a symbolic euphemism signifying destruction or a destructive force emanating from or being generated at the command of Deity. Joseph Fielding McConkie and Donald W. Parry, in their A Guide to Scriptural Symbols, explained it as follows—
“The east wind is a destructive wind which originates in the east, the symbolic direction of Deity’s presence. Also called ‘the wind of the Lord’ (Hosea 13:15), it is ‘prepared’ by God (Jonah 4:8) for the purpose of destroying the ungodly and unrighteous. The Lord has stated, ‘If my people shall sow filthiness they shall reap the east wind, which bringeth immediate destruction’ (Mosiah 7:31). Hence they are ‘smitten with the east wind’ ” (Mosiah 12:6; see also Job 27:21).
