Testament of Levi 9

And after two days I and Judah went up to Isaac after our father; and the father of my father blessed me according to all the words of the visions which I had seen: and he would not come with us to Bethel. And when we came to Bethel, my father Jacob saw in a vision concerning me, that I should be to them for a priest unto the Lord; and he rose up early in the morning, and paid tithes of all to the Lord through me. And we came to Hebron to dwell there, and Isaac called me continually to put me in remembrance of the law of the Lord, even as the angel of God showed to me. And he taught me the law of the priesthood, of sacrifices, whole burnt-offerings, first-fruits, free-will offerings, thank-offerings. And each day he was instructing me, and was busied for me before the Lord. And he said to me, Take heed, my child, of the spirit of fornication; for this shall continue, and shall by thy seed pollute the holy things. Take therefore to thyself, while yet thou art young, a wife, not having blemish, nor yet polluted, nor of the race of the Philistines or Gentiles. And before entering into the holy place, bathe; and when thou offerest the sacrifice, wash; and again when thou finishest the sacrifice, wash. Of twelve trees ever having leaves, offer up ''the fruits'' to the Lord, as also Abraham taught me; and of every clean beast and clean bird offer a sacrifice to the Lord, and of every firstling and of wine offer first-fruits; and every sacrifice thou shalt salt with salt.
