Comentario sobre Génesis 39:21

ויט אליו חסד AND CAUSED HIM TO FIND FAVOUR — so that he was liked by all who saw him. We have the expression חסד in a like sense in the Mishna (Baraitha): “a handsome bride liked by all (חסודה)” (Ketubot 17a).

ויהי ה׳ את יוסף. G'd was with Joseph. The meaning of this verse is that when a human being enjoys divine protection people around him are also influenced by the fact that such a person enjoys G'd's help. It was natural then that Joseph should find favour in the eyes of those who came into contact with him. G'd had to especially influence the warden of the prison to take a liking to Joseph as a righteous person [and therefore innocent, the victim of a miscarriage of justice. Ed.]

And extended kindness to him. The word “extended” implies more than was natural. Even the prisoners, who are usually cruel individuals, treated Yoseif with kindness and respect.
