Genesis 12:16

He had sheep. Of the domestic animals here mentioned, only the camel was still uncommon at this time. It was not entirely unknown, however, as a number of figurines of laden camels found in tombs of the third and second millenniums B.C. prove. The horse had not yet been introduced into Egypt, and is not mentioned. Archeology points to the Asiatic Hyksos, who ruled in Egypt more than a century, as introducing the horse and chariot. Moses’ mention of horses in Joseph’s time and not in Abram’s time is evidence of his accurate knowledge of Egypt.
