Testament of Levi

1And the angel opened to me the gates of heaven, and I saw the holy temple, and the Most High upon a throne of glory. And He said to me, Levi, I have given thee the blessings of the priesthood until that I shall come and sojourn in the midst of Israel. Then the angel brought me to the earth, and gave me a shield and a sword, and said, Work vengeance on Shechem because of Dinah, and I will be with thee, because the Lord hath sent me. And I destroyed at that time the sons of Hamor, as it is written in the heavenly tablets. And I said to Him, I pray Thee, O Lord, tell me Thy name, that I may call upon Thee in a day of tribulation. And He said, I am the angel who intercedeth for the race of Israel, that He smite them not utterly, because every evil spirit attacketh it. And after these things I was as it were awaked, and blessed the Most High, and the angel that intercedeth for the race of Israel, and for all the righteous.
