Key personalities are Habakkuk and the Babylonians. As is true of the many other prophets, Habakkuk is a short book. The information in it was vital since it carried God's message to His people. Its purpose was that Habakkuk was announcing a familiar message of judgment. He was identifying the wickedness and sin of Judah before them. Habakkuk declared that God is the "Rock" (1:2) and that they would be judged.
