In Romans 12:19 Paul writes, Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, 'Vengeance is mine, I will repay, says the Lord.'
The assurance of Scripture is that the Lord will repay all the cruelty and injustice done in his world. This ultimate judgment is seen by John in his vision in Revelation 18:4–8 where Babylon represents all the oppression and cruelty done by the powers of the world.
What happens in Nineveh is simply a foretaste of the Lord of hosts calling cruelty and oppression in his world to account.
14 Voici, j'en veux à toi, dit l'Eternel des armées; Je réduirai tes chars en fumée, L'épée dévorera tes lionceaux, J'arracherai du pays ta proie, Et l'on n'entendra plus la voix de tes messagers.
