three horses. And the Baraita further reported that the Roman Empire made chariots drawn by four horses. The Pirke De-Rabbi Eliezer taught that when Joseph rode in his chariot (as described in ), the Egyptian girls climbed up the walls to see him and threw him rings of gold so that he might look at them and they could see the beauty of his figure.
