This last chapter is clearly a prayer or hymn of Habakkuk the prophet. Like the psalms attributed to David, it may not have been written by him, but inspired by Habakkuk. They were to sing this using the melody of Shigionoth or a lamentation. Thus, this hymn or prayer may have been used in their worship services.
Yahweh responded that he was devising some evil against these wicked people. They would wear a yoke on their necks, so that they could not walk around in a haughty manner. There would be an evil time for them on Yahweh’s appointed day. People would sing a taunting song against them as they would be wailing in a lamentation. They would admit that they would be ruined, because Yahweh had altered their inheritance. He had sent them off as captives, so that their fields would be divided up among other people. Yahweh’s response to these evil doers was an exile captivity with the loss of their land.
