Rashi on Genesis 39:6/רש"י על בראשית ל״ט:ו׳

1AND HE KNEW NOT AUGHT HE HAD — he paid no attention to anything.

2כי אם הלחם SAVE THE BREAD — this means his wife, but Scripture uses here a euphemism (Genesis Rabbah 86:6) (cf. Joseph’s own words in Genesis 39:9).

3ויהי יוסף יפה תאר AND JOSEPH WAS OF BEAUTIFUL FORM — As soon as he saw that he was ruler (in the house) he began to eat and drink and curl his hair. The Holy One, blessed be He, said to him, “Your father is mourning and you curl your hair! I will let a bear loose against you” (Midrash Tanchuma, Vayeshev 8). Immediately.
