war song freestyle

After the interesting narrative the chapter before, it seems kind of strange that there would be a chapter that's entirely a song... but given the pattern of many of the stories of the Old Testament, one might notice that great events / victories / miracles / etc. are always accompanied by praise and people's response to God.

The song mentions all the details of the story, the main heroes, and making mention of all the tribes of Israel that helped defeat Sisera. But the last verse especially caught my eye:

"So may all your enemies perish, O LORD!
But may they who love you be like the sun
when it rises in its strength."

It's an interesting analogy that they make, saying that people who love the Lord should be as like the sun at it's hottest point in the day - but what exactly does that mean? I guess it depends on what characteristics you'd ascribe to a high noon sun, but the author cuts off the song.
