Definition of Ahuzzath

There are three wife-sister narratives in Genesis, part of the Torah, all of which are strikingly similar. At the core of each is the tale of a Biblical Patriarch, who has come to be in the land of a powerful foreign overlord who misidentifies the Patriarch's wife as the Patriarch's sister, and consequently attempts to wed her himself. The overlord later finds out his error. Two of the three stories are similar in many other details, including the antagonist's name, Abimelech, although this could be construed as being a royal title, or a family name.
