'Difficult' in the Bible

When the queen of Sheba heard about Solomon's reputation, she traveled to Jerusalem and tested him with difficult questions. She brought along a large retinue, camels laden with spices, and lots of gold and precious stones. Upon her arrival, she spoke with Solomon about everything that was on her mind.

In Jerusalem, Jehoshaphat also appointed certain descendants of Levi, priests, and family leaders of Israel to render verdicts for the LORD and to decide difficult cases. Their offices were in Jerusalem.
