Habakkuk was an early contemporary of Jeremiah, most likely prophesying from 609-606 B.C. He prophesied immediately before Judah went into captivity in 605 B.C. to Babylon. We might call Habakkuk the questioning prophet. He posed two questions, one in 1:2-4 and one in 1:12-17. The answer of the LORD came in 1:5-11 and in 2:2-20. The book ends with a magnificent prayer/song of Habakkuk in chapter 3.
