'Song' in the Bible

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

It shall happen, when many evils and troubles are come on 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 swore."

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

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

Moses came and spoke all the words of this song in the ears of the people, he and Joshua the son of Nun.
