'Song' in the Bible

“Now therefore, write this song for yourselves, and teach it to the sons of Israel; put it on their lips, so that this song may be a witness for Me against the sons of Israel.

Then it shall come about, when many evils and troubles have come upon them, that this song will testify before them as a witness (for it shall not be forgotten from the lips of their descendants); for I know their intent which they are developing today, before I have brought them into the land which I swore.”

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

Then Moses spoke in the hearing of all the assembly of Israel the words of this song, until they were complete:

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