Sirach 31:15

15 Judge not thy neighbour by thyself: and be discreet in every point.

Sirach 31:15 In-Context

13 Remember that a wicked eye is an evil thing: and what is created more wicked than an eye? therefore it weepeth upon every occasion.
14 Stretch not thine hand whithersoever it looketh, and thrust it not with him into the dish.
15 Judge not thy neighbour by thyself: and be discreet in every point.
16 Eat as it becometh a man, those things which are set before thee; and devour note, lest thou be hated.
17 Leave off first for manners' sake; and be not unsatiable, lest thou offend.
