After addressing the dangers of corrupt passions and possessions, Isaiah turns to an even deeper issue—corrupt principles. When greed and indulgence dominate society, the next inevitable step is the distortion of truth itself. In Isaiah 5:18-23, the prophet condemns those who redefine morality, calling evil good and good evil, embracing deception, arrogance, and injustice. This woe highlights the tragic reality that when people reject God's standard, they create their own, leading to widespread moral decay.
