'World' in the Bible

He said to his daughters, "So where is he? Why in the world did you leave the man? Call him, so that he may eat a meal with us."

When it was reported to the king of Egypt that the people had fled, the heart of Pharaoh and his servants was turned against the people, and the king and his servants said, "What in the world have we done? For we have released the people of Israel from serving us!"

and they said to Moses, "Is it because there are no graves in Egypt that you have taken us away to die in the desert? What in the world have you done to us by bringing us out of Egypt?

But the people were very thirsty there for water, and they murmured against Moses and said, "Why in the world did you bring us up out of Egypt -- to kill us and our children and our cattle with thirst?"
