Deuteronomy 31:22

Moses therefore wrote this song the same day
The same day it was dictated to him by divine inspiration; he wrote it, as Josephus says ^F4,

``in hexameter verse, which he left in the holy Bible or book (the Pentateuch), containing (as he adds) a prophecy of things future, according to which all things have been done, and are done; and in nothing of it has he erred from the truth;''

and taught it the children of Israel;
instructed them in the meaning of it, directed them to repeat it frequently, to lay it up in their memories, and often meditate upon it; as being a divine composition, and of great importance, as the consideration of it will make appear.
