name as “Potiphar,” but afterwards records his name as “Potiphera” (and the ending of his name, , fera, alludes to the word feirio, indicating his mutilation). A Midrash taught that from the moment Joseph arrived in Potiphar's house (in the words of ), "The Lord was with Joseph, and he was successful . . . and his master saw that the Lord was with him." But the Midrash questioned whether the wicked Potiphar could see that God was with Joseph. So the Midrash interpreted the words "the Lord was with Joseph" in to mean that God's Name never left Joseph's lips. When Joseph came to minister to Potiphar, he would whisper a prayer that God grant him favor in God's eyes and in the eyes of all who saw him. Potiphar asked Joseph what he was whispering and whether Joseph was employing sorcery against him. Joseph replied that he was praying that he should find favor with Potiphar.

When asked why he left the eleven to follow the one, he replied that he was not concerned that wine carried by the eleven in the street would be rendered impure because it was used for idolatry, but he was concerned that the wine carried into the nonbeliever's shop might be. Similarly, Jacob's other sons were grown up and under their father's control, but Joseph was young and away from his father's supervision. Therefore, in the words of , "the Lord was with Joseph." The Tosefta deduced from that before Joseph arrived, Potiphar's house had not received a blessing, and that it was because of Joseph's arrival that Potiphar's house was blessed thereafter. The Pesikta Rabbati taught that Joseph guarded himself against lechery and murder. That he guarded himself against lechery is demonstrated by the
