Ben Sira 42:8

8 Do not be ashamed to instruct the stupid or foolish or the aged man who quarrels with the young. Then you will be truly instructed, and will be approved before all men.

Ben Sira 42:8 In-Context

6 Where there is an evil wife, a seal is a good thing; and where there are many hands, lock things up.
7 Whatever you deal out, let it be by number and weight, and make a record of all that you give out or take in.
8 Do not be ashamed to instruct the stupid or foolish or the aged man who quarrels with the young. Then you will be truly instructed, and will be approved before all men.
9 A daughter keeps her father secretly wakeful, and worry over her robs him of sleep; when she is young, lest she do not marry, or if married, lest she be hated;
10 while a virgin, lest she be defiled or become pregnant in her father's house; or having a husband, lest she prove unfaithful, or, though married, lest she be barren.
