Commentary for Genesis 39:15

וינס ויוצא החוצה, “he fled, leaving the house.” As a reward for Joseph’s fleeing the presence of his master’s wife on that occasion, G–d told him that He would reward him when the sea of reeds fled at the approach of Joseph’s coffin when the Israelites were facing the sea with the Egyptians threatening them from behind. (Tanchuma on parshat Nasso, section 30, interprets Psalms: 114,3: הים ראה וינוס, “the sea saw and fled” as meaning just that.)

ויעזב את בגדו אצלי, “he left his outer garment in my hands;” in preparation of raping me. He was not able o retrieve it until I started yelling, when he decided to flee.
