20. Rabbi Yosi said, It is written, "this poem," THAT IS, "NOW THEREFORE WRITE THIS POEM FOR YOURSELVES." Could it be called a poem? IT SHOULD HAVE SAID 'THIS TORAH.' Rabbi Yitzchak said, It is surely a poem. As a poem is drawn through the Holy Spirit from above downwards, SO these words also were drawn through the Holy Spirit from above downwards. This is why Moses spoke of a poem.
