'Idea' in the Bible

And when the children of Israel saw it, they said to one another, What is it? for they had no idea what it was. And Moses said to them, It is the bread which the Lord has given you for your food.

And when the people saw that Moses was a long time coming down from the mountain, they all came to Aaron and said to him, Come, make us a god to go before us: as for this Moses, who took us up out of the land of Egypt, we have no idea what has become of him.

For they said to me, Make us a god to go before us: as for this Moses, who took us up out of the land of Egypt, we have no idea what has come to him.
