Sirach 8:4LXX

2Contend not with a rich man, lest he bring an action against thee.

3For gold and silver hath destroyed many, and hath reached even to the heart of kings, and perverted them.

4Strive not with a man that is full of tongue, and heap not wood upon his fire.

5Communicate not with an ignorant man, lest he speak ill of thy family.

6Despise not a man that turneth away from sin, nor reproach him therewith: remember that we are all worthy of reproof.
