Ecclesiastes 10:19-20

New Revised Standard Version, Anglicised

¹⁹ Feasts are made for laughter;
    wine gladdens life,
    and money meets every need.
²⁰ Do not curse the king, even in your thoughts,
    or curse the rich, even in your bedroom;
for a bird of the air may carry your voice,
    or some winged creature tell the matter.
