“When the Babylonians
Heard about the dragon,
They were very indignant.
They conspired
Against the king.
They said.
‘The king
Has become a Jew.
He has destroyed Bel.
He has killed the dragon.
He has slaughtered the priests.’”
The Babylonians were upset at the king, after they heard what Daniel had done to the dragon. They were indignant. Thus, they conspired against the king. They were saying the king was becoming Jewish. He had destroyed their idol god Bel and the mysterious dragon god that they had worshipped. Besides that, the king had killed all the priests of the Bel temple. They were concerned about the Jewish influence of Daniel on their king.
