'Understanding' in the Bible

All the men of thy confederacy have brought thee on thy way, even to the border: the men that were at peace with thee have deceived thee, and prevailed against thee; they that eat thy bread lay a snare under thee: there is no understanding in him.

Shall I not in that day, saith Jehovah, destroy the wise men out of Edom, and understanding out of the mount of Esau?
