'Difficult' in the Bible

What the king is asking is so difficult that no one can make it known to him except the gods, whose dwelling is not with mortals.”

"Belteshazzar, chief of the diviners, since I know that the spirit of the holy gods is within you, and no mystery too difficult for you, explain to me the vision of my dream that I saw, along with its interpretation.

because he was found to have an extraordinary spirit, knowledge, and understanding, along with an ability to interpret dreams, explain riddles, and solve difficult problems. His name is Daniel, whom the king renamed Belteshazzar. Call for Daniel, and he will reveal the meaning of the writing."

However, I've heard that you can provide meaning and interpretation, and that you can solve difficult problems. If you are able to read the writing and report its meaning, you will be clothed in purple, have a gold chain placed around your neck, and you will become the third highest ruler in the kingdom."
