Ecclesiastes 10:2KJV

1Dead flies cause the ointment of the apothecary to send forth a stinking savour: a little folly him that is in reputation for wisdom honour.

2A wise man's heart at his right hand; but a fool's heart at his left.

3Yea also, when he that is a fool walketh by the way, his wisdom faileth , and he saith to every one he a fool.

4If the spirit of the ruler rise up against thee, leave not thy place; for yielding pacifieth great offences.
