'Knotty' in the Bible

This was because an extraordinary spirit, knowledge and insight, interpretation of dreams, explanation of enigmas and solving of difficult problems were found in this Daniel, whom the king named Belteshazzar. Let Daniel now be summoned and he will declare the interpretation.”

But I personally have heard about you, that you are able to give interpretations and solve difficult problems. Now if you are able to read the inscription and make its interpretation known to me, you will be clothed with purple and wear a necklace of gold around your neck, and you will have authority as the third ruler in the kingdom.”
