'Song' in the Bible

Now therefore write ye this song for you, and teach thou it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel.

And it shall come to pass, when many evils and troubles are come upon them, that this song shall testify before them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they frame this day, before I have brought them into the land which I sware.

So Moses wrote this song the same day, and taught it the children of Israel.

And Moses spake in the ears of all the assembly of Israel the words of this song, until they were finished.

And Moses came and spake all the words of this song in the ears of the people, he, and Hoshea the son of Nun.
