פירוש על יחזקאל 33:24

Abraham was one This is one of four things that Rabbi Akiva interpreted [in one way] and which his disciple, Rabbi Shimon ben Yochai, did not interpret as he did. Rabbi Shimon interpreted it in this manner: Abraham, who was commanded with only one commandment [namely circumcision], inherited the land. We, then, who have been commanded with many commandments, should surely have the land given to us for an inheritance (Tosefta Sotah 6:7). This is what the prophet answers them.
