What does Genesis 39:6 mean?
An employer who feels the need to make every decision, giving no trust to their employees, is sometimes called a "micro-manager." We have no information of whether Potiphar was a natural micro-manager, but the Bible is clear he was not that way with his captive slave, Joseph (Genesis 39:1). Joseph was so successful in overseeing all of Potiphar's household, and the Lord's blessings on the household were so abundant, that Potiphar stopped concerning himself with any of the household business. He just let Joseph handle it all (Genesis 39:2–5).Potiphar's only concern, when it came to his household, was what food he would eat. Perhaps this also refers to his most private affairs. Aside from those, Potiphar was convinced Joseph would handle everything as well or better than he could. Again, Potiphar clearly understood that Joseph's success came because of the power and blessing of Joseph's God. He wisely chose to stay out of the way and allow that to continue.
Beyond merely being successful and respected, Joseph was a good-looking young man. The description given here is the same as the compliment paid to his mother, Rachel (Genesis 29:17). Apparently, Rachel's son Joseph was stunning to look at.
Of course, some advantages come with drawbacks. Joseph's good looks will become a liability at this moment in his life, presenting him with temptation in the form of his master's wife (Genesis 39:7).
