In Exodus Chapter 1, there are amazingly only two midwives for all the Hebrew women in Egypt. They are called Shiphrah, "to glisten, make fair/goodly, brightness (garnish)" and Puah, "to glitter, brilliancy". These epithets would correspond to Isis and Nephthys, who were called the "midwives". In ancient Egypt childbirths were attended by two midwives who represented these two goddesses. So, it seems the Biblical account is a memory of that culture in which all midwives played the roles of Isis and Nephthys in helping to deliver babies.
