Yitskaq Ben-Abram (893 - 1073) was the second son of Abram and Hagar. Having been born to Hagar after fouteen years of infertility, he became Abram's favorite son. This would cause strife with Ishmael, but the brothers would reconcile after their mother's death. For the most part, Yitskaq lived in the shadow of his brother's success, taking as a wife his second cousin Ribqah who proved to have fertility problems aleviated by Egyptian medicine.
