Sirach 31:20

20 Sound sleep cometh of moderate eating: he riseth early, and his wits are with him: but the pain of watching, and choler, and pangs of the belly, are with an unsatiable man.

Sirach 31:20 In-Context

18 When thou sittest among many, reach not thine hand out first of all.
19 A very little is sufficient for a man well nurtured, and he fetcheth not his wind short upon his bed.
20 Sound sleep cometh of moderate eating: he riseth early, and his wits are with him: but the pain of watching, and choler, and pangs of the belly, are with an unsatiable man.
21 And if thou hast been forced to eat, arise, go forth, vomit, and thou shalt have rest.
22 My son, hear me, and despise me not, and at the last thou shalt find as I told thee: in all thy works be quick, so shall there no sickness come unto thee.
