Genesis 39:6

a. And he left all that he had in Joseph's hand; and he knew not aught he had, save the bread which he did eat. So absolute was Potiphar's confidence in Joseph that he placed into his hands his entire business and did not concern himself with any part of its management. He was only interested in, and concerned about, his food, about his meals. This was not mere Oriental indolence, but also a good share of Oriental wisdom, for the more he left Joseph to his own devices, the better off he was, the wealthier he became.

b. And Joseph was a goodly person, and well favored. He was a handsome young man, and well proportioned, well built.
