Bel 1:11

11 Then they all went with the king into Bel's temple, where the priests said to the king, "Your Majesty, we will go out and let you place the food on the table and prepare the wine. When you leave, you may lock the door behind you and seal it with the royal seal.

Bel 1:11 In-Context

11 Then they all went with the king into Bel's temple, where the priests said to the king, "Your Majesty, we will go out and let you place the food on the table and prepare the wine. When you leave, you may lock the door behind you and seal it with the royal seal.
12 In the morning when you return, if you find that Bel has not eaten everything, you can put us to death. But if he has, Daniel will die for making false accusations against us."
13 But the priests were not worried, because they had made a secret entrance underneath a table in the temple, so that they could go in every night and eat the offerings.
