“Stolen waters.” A not-so-veiled reference to sex. Women were often compared to wells, springs, or fountains (cp. Song 4:12). She was luring the man with sexual pleasure, but other fleshly pleasures were being offered as well. The reference to “stolen” shows that the woman was open about her being married (something that in any case would have been quickly obvious to the man she was seducing), showing that foolish and evil people are not ignorant about their sin, but rather simply don’t care about it and have no ethical problem defying God and hurting others.
“food.” The Hebrew is literally “bread,” but it is used for food in general.
