Sirach 31:17

17 Leave off first for manners' sake; and be not unsatiable, lest thou offend.

Sirach 31:17 In-Context

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.
18 When thou sittest among many, reach not thine hand out first of all.
19 A very little is sufficient for a man well nurtured, and he fetcheth not his wind short upon his bed.
