Wisdom of Ben Sira 31:18-20

New Catholic Bible

¹⁸ If you are dining with a large group,
    do not reach out your hand before the others.
¹⁹ A small portion is sufficient for someone of good upbringing;
    when he lies down, he experiences no discomfort.
²⁰ Moderate eating ensures sound sleep;
    such a man rises early and feels refreshed.
However, sleeplessness, nausea, and colic
    are the lot of the glutton.
