This verb means to pay penalty or undergo punishment for wrong. In 2 Thessalonians 1:9, Paul describes the fate of those who reject the gospel: 'They will pay the penalty of eternal destruction.' The verb emphasizes the judicial nature of eschatological judgment—this is debt paid, penalty exacted. Classical usage included paying fines or suffering consequences. The cross-linguistic rendering shows consistent judicial emphasis: Spanish 'pagarán' (they will pay), French preserving Greek form, German 'büssen' (atone/pay). This is justice satisfied through penalty.
