You could say that the surrogate mother of all surrogate mothers was Hagar, servant to Sarai in the Old Testament. Sarai, later known as Sarah, had fertility woes. So she pleaded with her husband β Abram, before he became Abraham β to lie with Hagar and do what needed to be done. βIt may be that I may obtain children by her,β she said, as rendered in the King James Version of Genesis 16:2. Her plan worked splendidly. Hagar conceived a son. Call him Ishmael.
