DEUT909 Arrogance supported by power can pose a serious threat to the welfare of mankind. An ordinary arrogant individual can be isolated by society and thus neutralized. Such treatment is ineffective in the case of arrogant kings and tyrants. The Bible enjoined the kings of Israel to place a copy of the Pentateuch in their libraries. It was hoped that its precepts would exercise a moderating influence upon them. The king was to study the Bible to the end "so that he may learn to fear the Lord his God, to keep all the words of this law… that his heart may not be moved by arrogance to lift him up above his brethren" [this and following verses].
