Now is she without, now in the streets, and lieth in wait at every corner.)
– Proverbs 7:12
It’s not that the adulteress just wanders about idly and happens to come to trouble. Though she doesn’t want to give that appearance, she is industriously searching. Lying in wait means to lurk or set an ambush. It’s obvious why Solomon admonished the young man to stay away and not go near her door (Proverbs 5:8). While the young man may wander aimlessly, she has a purpose.
