Solomon wrote 3000 proverbs and collected other wise sayings; some made it into the book of Proverbs. These chapters are the last from the first collection of Solomon’s proverbs.
19:15 Laziness brings on deep sleep;
an idle person will suffer hunger.
20:13 Do not love sleep, or else you will come to poverty;
open your eyes, and you will have plenty of bread.
24:33 A little sleep, a little slumber,
a little folding of the hands to rest,
and poverty will come upon you like a robber,
and want, like an armed warrior.
