Genesis 39:6

And he left all he had in Joseph's hand;.... His master took no care of anything, but committed all to him, trusted him with his money and with his accounts, and with the management of all his affairs; such confidence did he put in him;

and he knew not aught he had, save the bread which he did eat; some understand this of Joseph, that though he had all his master's substance in his hands, yet he made no use of it for himself, enjoyed nothing of it but the bread he ate; and it is the observation of a Jewish writer p, that he ate nothing but dry bread, and yet, like Daniel and his companions, was well favoured and of a goodly countenance, as in the next clause: but it is better to interpret it of Joseph's master, who was so satisfied with Joseph's good management and fidelity, that he never concerned himself about his affairs, how they stood or what money he had in his house, or what effects he was possessed of; all that he regarded was his food, and perhaps he knew not what that would be till it came to his table; though some take the expression in this light, that he gave himself unto a luxurious life, regarding nothing but eating and drinking, and taking his pleasure, having so good and faithful a servant: but according to Aben Ezra the sense is, that Joseph had all committed to his care, excepting the bread, or making provision of that for him and his family, which he might not touch being an Hebrew, and had all things common with him but that, see Genesis 43:32; which is a much better sense than what the Targum of Jonathan and Jarchi give, who interpret bread of his wife, whom only he reserved for himself of all things in his house;

and Joseph was [a] goodly [person], and well favoured; being like his mother, as Aben Ezra observes, see Genesis 29:17; this is remarked for the sake of what follows, and as leading on to that.
