'Matter' in the Bible

In every matter of wisdom and insight the king asked them about, he found them to be ten times better than any of the magicians and astrologers that were in his entire empire.

He inquired of Arioch the king's deputy, "Why is the decree from the king so urgent?" Then Arioch informed Daniel about the matter.

Then Daniel went to his home and informed his friends Hananiah, Mishael, and Azariah of the matter.

"This is the conclusion of the matter. As for me, Daniel, my thoughts troubled me greatly, and the color drained from my face. But I kept the matter to myself."
