וַיְהִ֤י יְהוָה֙ אֶת־יוֹסֵ֔ף וַיֵּ֥ט אֵלָ֖יו חָ֑סֶד וַיִּתֵּ֣ן חִנּ֔וֹ בְּעֵינֵ֖י שַׂ֥ר בֵּית־הַסֹּֽהַר׃
But the LORD was with Joseph, and showed kindness unto him, and gave him favour in the sight of the keeper of the prison.
Rashi on Genesis
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).
Or HaChaim on Genesis
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.]
Haamek Davar on Genesis
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.
