[20:17] 1 tn Heb “bread of deceit” (so KJV, NAB). This refers to food gained through dishonest means. The term “bread” is a synecdoche of specific for general, referring to anything obtained by fraud, including food.
[20:17] 3 sn The image of food and eating is carried throughout the proverb. Food taken by fraud seems sweet at first, but afterward it is not. To end up with a mouth full of gravel (a mass of small particles; e.g., Job 20:14-15; Lam 3:16) implies by comparison that what has been taken by fraud will be worthless and useless and certainly in the way (like food turning into sand and dirt).
