'Difficult' in the Bible
The queen of Sheba heard of Solomon’s fame, so she came to test Solomon with difficult questions at Jerusalem with a very large entourage, with camels bearing spices, gold in abundance, and precious stones. She came to Solomon and spoke with him about everything that was on her mind.
So Solomon answered all her questions; nothing was too difficult for Solomon to explain to her.
“Your father made our yoke difficult. Therefore, lighten your father’s harsh service and the heavy yoke he put on us, and we will serve you.”
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.
