The Book of the Wars of Yahweh

There are at least to my knowledge two different books that are referenced in the Old Testament that we don't know anything about except for those particular references. Now what these seem to be are some kind of collections of songs or poetry that were the Israelites way of putting to music putting to poetry various aspects of their journey and over the early years as they worked away toward the promised land. So it's kind of a interesting I think uh trivial bit of trivia if you will That there were or besides the Bible what we have in the Bible there were other books in ancient Israel which recorded some of the experiences of Israel and translated those experiences into poetry.
