Shiphrah and Puah
According to Exodus 1:15-21, these Hebrew midwives prevented a genocide of killing Hebrew boys. They were ordered by the Pharoah to deliver babies from Hebrew families but if it was a boy, they would have to kill it. Knowing in their hearts that this was a dishonor to God, they did not do it. The Pharaoh was upset and asked the why they did not follow his order. This is what they said: "Hebrew women are not like Egyptian women; they are vigorous and give birth before the midwives arrive." Because they displayed obedience and honor to God, He blessed them with families of their own. Without them, Moses and many other Biblical men would not have been born.
