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.
This last chapter of the Book of Daniel is often referred to as the story of Bel, the god, and the dragon. Daniel will show how each one was useless. Once again, this chapter is only in the Greek Septuagint, so that it is often called apocryphal. This story takes place at the later part of the life of Daniel, since Cyrus the Persian (598-530 BCE) was the King. His rule in Persia began in 559 BCE and lasted about 30 years. Here, he is still only the king of Persia that he received from his father, King Astyages (585-550 BCE). The sister of King Astyages was the wife of King Nebuchadnezzar of Babylon. Thus, you can see the connection, as Cyprus would have been the nephew of the Babylonian king. Eventually, Cyrus took over Babylon in 539 BCE.
Gabriel had heard the prayer and supplications that Daniel had made to God. Thus, that this was the Angel Gabriel is not out of place, especially based on the last chapter. This Gabriel said to Daniel that he had come to give him wisdom and understanding. Something that he had said at the beginning of his prayers and supplications needed a further explanation. There was no doubt that Daniel was greatly loved. However, he had to consider the words and vision that was about to take place.
Daniel seemed to have a unique role. He already had an important role under King Belshazzar (550-539 BCE) of Babylon, as indicated at the end of the last chapter. Here, he took on a bigger role as president of the whole country. However, Daniel would be an old man at this time. First, he was 1 of the 3 presidents. Then the king decided to put in charge of everything because of his excellent spirit. Thus, this Judean exile Daniel was in charge in Persia and Babylon, just under the king.
Yahweh, via Ezekiel, seemed to praise the beauty of Tyre. The people of Tyre thought that they were perfect in beauty. As a city island, her borders were the sea all around her. Somehow her builders made her perfectly beautiful. This seems odd coming after the complete condemnation of Tyre, at the end of the last chapter. This was a strange lamentation about Tyre.
This letter of Jeremiah found as the last chapter in this book of Baruch ends with a comparison of these false wooden gods covered with gold and silver. The author compared them to a scarecrow in a cucumber bed that guarded nothing. They were compared to a thorn bush in a garden where birds sat on it. They were compared to a dead corpse in the dark. All of these useless items were like these useless idol gods. Even with purple or linen on them, they would still rot. They would be finally consumed and become a reproach to all. It was much better to be an upright person beyond reproach than any of these gods. So ends the letter of Jeremiah in the Book of Baruch.
