Kabbalah su Salmi 3:4

Rabbi Yosi opened the discussion by saying, "But you, Hashem, are a shield for me; my glory, and the one who lifts up my head" (Ps. 3:4). David said, Even if all the people of the world come and make war with me, "You, Hashem, are a shield for me." Come and behold, it is written, "a shield for me." David said to the Holy One, blessed be He, Master of the Universe, why is there no blessing that ends with my name, as there is for Abraham, of whom it is written, "I am your shield" (Gen. 15:1) and therefore it is said, 'the shield of Abraham.'
