In Yalkut Yehoshua 9, Osenath is styled a proselyte; and indeed
it might seem likely enough that Joseph induced her to worship
the true God. The Targum of Jonathan agrees with the version of
the Midrash above, while another tradition makes Joseph marry
Zuleika, the virgin widow of Potiphar, and says that she was the
same woman that is called Osenath (_Koran_, note to p. 193).
When Joseph's brethren recognized him, and were about to kill him, an
angel came down and dispersed them to the four corners of the house.
Then Judah screamed with such a loud voice that all the walls of Egypt
were leveled with the dust, all the beasts were smitten to the ground,
and Joseph and Pharaoh, their teeth having fallen out, were cast down
from their thrones; while all the men that stood before Joseph had their
heads twisted round with their faces toward their backs, and so they
remained till the day of their death; as it is said (Job iv. 10), "The
roaring of the lion (Judah), and the voice of the fierce lion," etc.
