Many times in just a few verses (Genesis 39), we’re told that the Lord was with Joseph. Joseph knew who he was, whose he was, and just what that meant. Joseph had made sacred covenants, been taught the gospel of Jesus Christ, and desired to live the Lord’s law (particularly the law of chastity here). He could not defile himself by compromising his (and the Lord’s) standards. When he realized he was in a dangerous place, full of wickedness, he fled. That means he removed himself from that horrid situation immediately and got away.
