Remove thy way far from her, and come not nigh the door of her house: Lest thou give thine honour unto others, and thy years unto the cruel (Proverbs 5:8-9)
Don’t become intimate with a strange woman (or man). Don’t come near the door of her (or his) house.
As soon as you come into her (or his) house, then you shall be drawn into darkness.
As soon as you open her (or his) door, you shall give your honor to her (or him), and your years to the cruel.
‘Be the salt of the earth’
