Genesis 39:10 - Avoid falling under the spell of passion.

And it came to pass, as she spake to Joseph day by day, that he hearkened not unto her, to lie by her, or to be with her.

she spake to Joseph day by day - Potiphar's wife's intense desire to have sex with Joseph was relentless. Not only did Joseph continually refuse her illicit sex offers, he also took care not to be with her. By avoiding her, she couldn't entice him with her smooth offers of how having sex with her would be harmless and something to be enjoyed (Proverbs 7:18). Don't believe the lie, sexual immorality is harmful and something not to be enjoyed.
