Genesis Chapter 41 verses 42 and 43 read: “Then Phar?aoh removed his signet ring from his own hand and put it on Joseph’s hand and clothed him with garments of fine linen and placed a necklace of gold around his neck. Moreover, he had him ride in the second chariot of honor that he had, and they would call out ahead of him, “A·vrékh!”. Thus he put him over all the land of Egypt.”
