And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.

My sister, or niece, according to those who say she was daughter of Aran, who thus must have had a different mother from Abraham; (Menochius) or, as we rather think, Sara was truly his half-sister, born of Thare by another wife. His adding truly, seems to restrain it to this sense; and we know that in those countries, marriages of such near relations were allowed, though not when both had the same parents.

He teaches them by way of story that from the very beginning he had a special relationship with God and that God had personally moved him from home and led him there so that the king might learn that he was one of those people who had great c...
