Righteous Sarah
Sarah was the wife of the Old Testament Patriarch Abraham and the mother of Isaac. At first she was called Sarai, and her name was changed to Sarah (Genesis 17:15-16). The three men who visited Abraham at the oak of Mamre told her that she would conceive and have a son (Genesis 18:10). She did not believe them at first, since she and her husband were old, but they insisted that she would bear a son in the spring. Their prediction was fulfilled, and God did as He had promised (Genesis 21:1-3). Saint Andrew Rublev depicts the three men as angels in his most famous icon. Sarah is praised in the New Testament for her faith (Hebrews 11:11) and also for her obedience (I Peter 3:6).
