Seder Eliyahu Zuta 2
One time I was walking on the way. A man found me, and went with me on the way of mitzvot, and he had mikra (ie: written law) but no mishnah (ie: oral law). And he said to me, "Rabbi, mikra was given to us from Mount Sinai. Mishnah was not given to us from Mount Sinai." And I said to him, "My son, mikra and mishnah were both of them said from the mouth of God." And what is the difference between mikra and mishnah?
To what can it be compared? To a king of flesh and blood who had two servants, and he loved them with a great love. He gave each of them a measure of wheat and a bundle of flax. One servant took the flax and wove a beautiful cloth, and took the wheat and made it into fine flour, and sifted it, and ground it, and kneaded it, and baked it, and set it on the table, and spread the beautiful cloth over it, and left it there until the king should come.
The other servant, however, did nothing at all. After some time, the king returned from a journey and came into his house. He said to his two servants, "My sons, bring to me what I gave you." One of them brought out the bread of fine flour, on the table, with the beautiful cloth spread over it. And the other of them brought out the wheat in a pile and the bundle of flax upon it. Woe for that shame! Woe for that disgrace!
Which one is more favored? You must admit it is the one who brought out the bread on the table with the beautiful cloth spread over it...
When the Holy One, blessed be God, gave the Torah to Israel, it was only given to them as wheat from which to bring forth fine flour, and as flax from which to weave a garment..."
