Sirach 31:16-18

Revised Standard Version

¹⁶ Eat like a human being what is set before you,
    and do not chew greedily, lest you be hated.
¹⁷ Be the first to stop eating, for the sake of good manners,
    and do not be insatiable, lest you give offense.
¹⁸ If you are seated among many persons,
    do not reach out your hand before they do.
