Of the Repeated Address of God to Abraham, in Which He Promised the Land of Canaan to Him and to His Seed
Abraham, then, having departed out of Haran in the seventy-fifth year of his own age, and in the hundred and forty-fifth of his father's, went with Lot, his brother's son, and Sarah his wife, into the land of Canaan, and came even to Sichem, where again he received the divine oracle, of which it is thus written: “And the Lord appeared unto Abram, and said unto him, Unto your seed will I give this land.” Nothing is promised here about that seed in which he is made the father of all nations, but only about that by which he is the father of the one Israelite nation; for by this seed that land was possessed.
