'Difficult' in the Bible

When the queen of Sheba heard about Solomon's reputation with the LORD, she came to test him with difficult questions.

So the king sought some advice and then built two golden calves and announced, "It's too difficult for you to travel to Jerusalem. So here are your gods, Israel, who brought you up from the land of Egypt!"

Later, the angel of the LORD came a second time, grabbed him, and said "Get up! Eat! The journey ahead is too difficult for you!"
