The phrase alludes to the biblical narrative where a specific sum was paid as a betrayal reward. It serves as a potent symbol of treachery and the devaluing of something sacred or of high worth. The amount is often used metaphorically to represent a price considered inadequate or insulting for a significant act of betrayal or a valuable asset.
Its importance lies in its cultural and historical resonance. The reference point is deeply embedded in Western literature, art, and moral discourse. It highlights the timeless human capacity for deceit and the consequences of prioritizing personal gain over ethical principles. Its continued use demonstrates the enduring power of biblical narratives to inform contemporary understanding of moral complexities.
