Daniel 6:11

Then these men assembled
Gathered together, and went in a body to Daniel's house; knowing his times of prayer, and where, and in what manner, he used to pray, to see if they could find him at it as aforetime; that so they might have to accuse him with it. Saadiah says, they found a girl, and asked her what Daniel was doing? she told him that Daniel was on his knees, praying to his God in his chamber; immediately they went, and found as she had said: and found Daniel praying and making supplication before his God;
they went into his house, and up into his chamber, the doors not being locked, pretending perhaps business with him, and saw him at his devotions; so that they were able, upon their own knowledge, to bring in an accusation against him for breach of the king's law, and prove it.
