'Troubled' in the Bible

It came about in the twentieth year of Artaxerxes, during the month of Nissan, the king was about to drink some wine that I was preparing for him. Now I had never looked troubled in his presence.

The king asked me, "Why do you look so troubled, since you're not ill? This cannot be anything else but troubles of the heart."

Then I was filled with fear. I replied to the king, "May the king live forever. Why shouldn't I be troubled, since the city where my ancestral sepulchers are located lies waste, with its gates burned by fire?"
