A.T. Robertson Commentary Luke 1:33

"and he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end." — Luke 1:33 (ASV)

Shall be no end (ουκ εστα τελος). Luke reports the perpetuity of this Davidic kingdom over the house of Jacob with no Pauline interpretation of the spiritual Israel though that was the true meaning as Luke knew. Joseph was of the house of David (Luke 1:27) and Mary also apparently (Luke 2:5).
