Just a shot in the dark, but Jews have a fifty year cycled event called Jubilee. It is basically used as a nullification of debts. (Property wise.) May be this is alluding to Jesus' perceived break with traditional Judaism? Seeing the first Jew would amount to admitting the contract has been broken. The land being currently controlled by Rome makes seeing Abraham a possible stab at renewed autonomy, too, i suppose.
Just guessing out loud here, I admit.
