The Book of Habakkuk is the eighth book of the 12 minor prophets of the Bible. It is attributed to the prophet Habakkuk, and was probably composed in the late 7th century BC. Of the three chapters in the book, the first two are a dialogue between Yahweh and the prophet. The message that "the just shall live by his faith" plays an important role in Christian thought. It is used in the Epistle to the Romans, Epistle to the Galatians, and the Epistle to the Hebrews as the starting point of the concept of faith.
