Daniel 6:10, 16, 20

But when Daniel learned that the law had been signed, he went home and knelt down as usual in his upstairs room, with its windows open toward Jerusalem. He prayed three times a day, just as he had always done, giving thanks to his God.

So at last the king gave orders for Daniel to be arrested and thrown into the den of lions. The king said to him, “May your God, whom you serve so faithfully, rescue you.”

When he got there, he called out in anguish, “Daniel, servant of the living God! Was your God, whom you serve so faithfully, able to rescue you from the lions?”
