Bel 1:19 In-Context

17 The king asked, "Have the seals been broken, Daniel?" "No, Your Majesty, they have not been broken," he replied.

18 As soon as the door was opened, the king saw the empty table and shouted, "You are great, O Bel! You really are a god."

19 But Daniel began to laugh and said to the king, "Before you enter the temple, look at the floor and tell me whose footprints you see there."

20 "I see the footprints of men, women, and children," said the king,

21 and he became so angry that he had the priests and their families arrested and brought to him. They showed him the secret doors through which they had come in each night to eat the food placed on the table.
