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.
The Scream of Judah That Shook Every Wall in Egypt
