"Blood" here is a metonym for murder, and "Zion" and "Jerusalem" are spoken of as if they were buildings. Micah speaks of the rich murdering people and sinning in other ways as if those activities were the bricks and wood with which people use to build houses. Alternate translation: "You commit murder and other horrible sins as you work to make Zion and Jerusalem great" or "You commit murder as you worship in Zion, and you commit other sins as you get rich in Jerusalem" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-metonymy]])
