Habakkuk, a book of prophecy, is concerned with the problem of unpunished evil in the world. It is revealed to Habakkuk that the Chaldean armies are to be God’s means of punishing the wicked and that evil will destroy itself. The book concludes with a poem of thanksgiving and great faith.

Habakkuk 2

2:3 For the vision is yet for an appointed time, but at the end it shall speak, and not lie: though it tarry, wait for it; because it will surely come, it will not tarry.
