Lyric discussion by JesusFChrist 

Manifest Destiny is a mindset that many Americans held during the 1820s and 1830s.

While the gold rush, growth of opportunity, and easier transport and communication grew in the United States, the need and desire to expand territory into the West was advocated. The native americans inhabiting the West didn't discourage them from moving in. Americans believed, by the power and will of God, that they were entitled to that land. It didn't matter if it was already inhabited or who it belonged to. They wanted to expand and find new opportunities for themselves and their families. "Said they were guided from above" is a reference to this. Americans used the word of God and the heavens above as an excuse to expand into the West at whatever cost, even if it meant expelling Natives from their homes and the land they inhabited.
