"Little is known about Habakkuk except that he was a contemporary of Jeremiah and a man of vigorous faith rooted deeply in the religious traditions of Israel. . . . The prediction of the coming Babylonian invasion (1:6) indicates that Habakkuk lived in Judah toward the end of Josiah's reign (640-609 B.C.) or at the beginning of Jehoiakim's (609-598). The prophecy is generally dated a little before or after the battle of Carchemish (605), when Egyptian forces, who had earlier gone to the aid of the last Assyrian king, were routed by the Babylonians under Nabopolassar and Nebuchadnezzar and were pursued as far as the Egyptian border (Jer 46)."
