There's been a lot of breaking down the RWBY songs to try and find out who/what they're about. I figure it may prove interesting to try linking songs through the repeated words/ideas to help figure out some of the more vague concepts. Below are lyrics (sometimes paraphrased) mashed together followed by plausible connections/meanings.
1. Were we born to fight and die, sacrificed by one huge lie? There's a day we will fight and not fall, we will stand and not crawl. Take the lives of those you need, but I'm not your Sacrifice. I won't crawl or fall for you.
The fight and die would be the lie but may be the general humans vs. grimm struggle, with their deaths becoming a sacrifice somehow. The person doing the sacrificing is deliberately taking out kingpins needed for their plan, but the hunters/huntresses will not bow down and crawl before the ones using grimm to achieve their sacrifices.
2. Truth will rise, revealed by mirrored eyes. In time, your heart will open minds and victory is in a simple soul. Beware that the light is fading and beware if 'the dark' returns. Even brilliant lights can cease to burn.
The one revealing the plan will have mirrored eyes (i relate this to Ruby's grey eyes, but maybe it's Weiss revealing SDC secrets). In time her heart will open up the minds of the ones making sacrifices and make them see the wrongdoing of their ways and/or resolve the conflict. Also, take care that hope/humanity is fading, and especially so if the grimm return (to their borders, or more specifically like in the failed train incident). Even pillars of hope can be extinguished no matter how bright or safe they may seem.
I also like the idea of using the last part for Yang. Beware that her good side is fading, beware if the dark (Raven) returns. Even brilliant lights (Gold, I Burn) can cease to burn (she can be corrupted).
3. We are miracles of ancient wonder.
Machines of war that fuel the fight.
Our faith is in the ancient ways.
Show the gods and deities what you are made of, and make the people bow down to your power.
This may mean those with powers were created by an older generation to fight off the Grimm and were considered to be ‘miracles’ at the time, but they quickly became machines of war meant to fight not only the Grimm. Everyone blindly accepts the older generation’s ideals. As a 'miracle', they could be considered gods and deities, and have now turned on the generation who doesn't have their power, keeping them bowing down and also overthrowing those of equal standing. (Kind of like how Cinder seems to be trying to take out humanity as if to show Ozpin what she is capable of.)
4. Legends are of Scatter (Summer/Ruby’s semblance), or are scattered.
The moon will sadly watch the roses die
The moon and sun were severed (
Ruby is represented as moon; think Summer, and Yang/Taiyang are represented as sun)
Hope and peace are lost forever.
Hate flowing caused the moon to shatter and raised the need for bloodshed.
The moon has since watched safely from above.
Suppose there is a legend about Scatter roaming around. Basically a destiny or fate behind it which falls under Ozpin’s you have grey eyes line (‘the one with grey eyes will wield Scatter and bring hope and peace to mankind’ or the sort). It would also give Cinder a reason to see Ruby as an equal enough to show herself and face off against her at the communcations tower. (Maybe the legend has Scatter ruining her plans.) Summer was the original one with scatter, and since her death has scattered herself. The moon (Summer) watching the roses die could refer to a rose wilting, which is not only how Adam's ability is portrayed, but is also the name of part of his weapon. When she died, the moon (Summer), and the sun (Taiyang) were severed from each other and hope and peace were considered to be lost forever. (The fated one is no longer among us.) Perhaps out of rage or hatred, a strong ability or weapon was unleashed, shattering the moon, which only caused more turmoil in and of itself. (Have fun thinking of Taiyang going berserk over the loss, Raven teleporting him to the moon, and having his punch of rage shatter it rather than Remnant). Since her death, Summer has watched over Ruby and Yang safely from above (heaven).
