Sirach 31:18-20

New Revised Standard Version Updated Edition

¹⁹ How ample a little is for the well-disciplined!
    They do not breathe heavily when in bed.
²⁰ Healthy sleep depends on moderate eating;
    they rise early and feel fit.
The distress of sleeplessness and of nausea
    and colic are with the glutton.^(B)
