12 thousand Acres refers to the 12 thousand acres promised (but never delivered), to African American slaves once freed from slavery. Kanye has invested in well over 12 thousand acres of property, especially in Wyoming. In Kanye’s idea he has freed himself from slavery by investing his money wisely and not on materialism, which is how slavery exists in modern America
The lyrics are direct quotes from the Bible in Daniel 2. Kanye was reading the Bible during his opera called “Nebuchadnezzar” (Named after the current king of Babylon in the book of Daniel) on Nov. 24th, 2019.
