Proverbs 8:5

Proverbs 9:1-5  
Wisdom hath builded her house, she hath hewn out her seven pillars:  She hath killed her beasts; she hath mingled her wine; she hath also furnished her table.  She hath sent forth her maidens: she crieth upon the highest places of the city,  Whoso is simple, let him turn in hither: as for him that wanteth understanding, she saith to him,  Come, eat of my bread, and drink of the wine which I have mingled.  

Proverbs 9:13-18  
A foolish woman is clamorous: she is simple, and knoweth nothing.  For she sitteth at the door of her house, on a seat in the high places of the city,  To call passengers who go right on their ways:  Whoso is simple, let him turn in hither: and as for him that wanteth understanding, she saith to him,  Stolen waters are sweet, and bread eaten in secret is pleasant.  But he knoweth not that the dead are there; and that her guests are in the depths of hell.
