Sirach 8:5LXX

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.

7Despise not a man in his old age; for we also shall become old.
