Daniel 4:6

Though he had experienced before that these wise men were fooled, and could do nothing either in telling or interpreting his dream, Da 2, yet he will try them once again, possibly because they might gain fresh credit with the king; or he would hear what they could do, and if they failed him, he would then make use of Daniel whom he had in reserve. Perhaps these Chaldean doctors and wizards shunned and scorned Daniel's company, and he was as much shy of theirs; therefore they came not together; but God had disposed of this whole scene, and, for the honour of his name, suffered Daniel not to be sent for till the last.
