7 Look not round about thee in the streets of the city, neither wander thou in the solitary place thereof.

9 Sit not at all with another man's wife, nor sit down with her in thine arms, and spend not thy money with her at the wine; lest thine heart incline unto her, and so through thy desire thou fall into destruction.
10 Forsake not an old friend; for the new is not comparable to him: a new friend is as new wine; when it is old, thou shalt drink it with pleasure.
