Stolen waters are sweet, and bread eaten in secret is pleasant.
All Commentaries on Proverbs 9:17 Go To Proverbs 9
Augustine of Hippo
AD 430
Bread is used in a good sense in “I am the living bread which came down from heaven,” but in a bad sense in “hidden bread is more pleasant.” Many other things are used in the same way. Those examples that I have mentioned create little doubt as to their meaning, for things ought not to be used as examples unless they are clear. There are, however, instances in which it is uncertain whether the signification is to be taken in a good sense or in an evil sense.
