Proverbs 9:13 A foolish woman is clamorous: she is simple, and knoweth nothing.
14 For she sitteth at the door of her house, on a seat in the high places of the city,
15 To call passengers who go right on their ways:
16 Whoso is simple, let him turn in hither: and as for him that wanteth understanding, she saith to him,
17 Stolen waters are sweet, and bread eaten in secret is pleasant.
18 But he knoweth not that the dead are there; and that her guests are in the depths of hell.
A foolish person is someone who does not know the ways of God. This person has no morals and their actions are the opposite of wisdom. Foolishness is a rejection of God and this kind of person knows nothing of any importance. Again we see where the harlot calls out to her victims and they are people who do not know God or have rejected Him. Those who partake of this sin or any sin are going the way of the world and because they have not wisdom they also lack understanding. Forbidden things always seem better and more exciting because of their danger and excitement This act of sin, as any sin, leads to hell and destruction and flattering words of folly lead to death. It is interesting that wisdom offered meat and wine to her guests and the foolish offers bread and water. It seems that the world wants only the forbidden fruit. Death and hell await the foolish that reject God.
