Targum su Genesi 32:25

And Jakob remained alone beyond the Jubeka; and an Angel contended with him in the likeness of a man. And he said, Hast thou not promised to give the tenth of all that is thine? And, behold, thou hast ten sons and one daughter: nevertheless thou hast not tithed them. Immediately he set apart the four firstborn of the four mothers, and there remained eight. And he began to number from Shimeon, and Levi came up for the tenth. Michael answered and said, Lord of the world, this is Thy lot. And on account of these things he (Michael) remained from God at the torrent till the column of the morning was ascending.
