'Song' in the Bible

Now write down for yourselves the following song and teach it to the Israelites. Put it into their very mouths so that this song may serve as my witness against the Israelites!

Then when many disasters and distresses overcome them this song will testify against them, for their descendants will not forget it. I know the intentions they have in mind today, even before I bring them to the land I have promised."

So on that day Moses wrote down this song and taught it to the Israelites,

Then Moses recited the words of this song from start to finish in the hearing of the whole assembly of Israel.

Then Moses went with Joshua son of Nun and recited all the words of this song to the people.
