Bel 1:8

8 At this the king became angry and called in all seventy of the priests of Bel. He said to them, "I warn you that you will be put to death, unless you can show me that it is Bel who is eating these offerings. If you prove to me that it is Bel, then I will have Daniel put to death for claiming that Bel is not a god." Daniel agreed to this proposal.
