C. F. Keil and Franz Delitzsch on Genesis 39:1-5

Gen 39:1-5

In Potiphar’s House. - Potiphar had bought him of the Ishmaelites, as is repeated in Gen 39:1 for the purpose of resuming the thread of the narrative; and Jehovah was with him, so that the prospered in the house of his Egyptian master. מצליח אישׁ: a man who has prosperity, to whom God causes all that he undertakes and does to prosper. When Potiphar perceived this, Joseph found favour in his eyes, and became his servant, whom he placed over his house (made manager of his household affairs), and to whom he entrusted all his property (כּל־ישׁ־לו Gen 39:4 = ישׁ־לו כּל־אשׁר Gen 39:5, Gen 39:6). This confidence in Joseph increased, when he perceived how the blessing of Jehovah (Joseph’s God) rested upon his property in the house and in the field; so that now “he left to Joseph everything that he had, and did not trouble himself אתּו (with or near him) about anything but his own eating.”
