'Answering' in the Bible

Shadrach, Meshach, and Abed-nego, answering Nebuchadnezzar the king, said, There is no need for us to give you an answer to this question.

Then Daniel, whose name was Belteshazzar, was at a loss for a time, his thoughts troubling him. The king made answer and said, Belteshazzar, do not be troubled by the dream or by the sense of it. Belteshazzar, answering, said, My lord, may the dream be about your haters, and its sense about those who are against you.

Because a most special spirit, and knowledge and reason and the power of reading dreams and unfolding dark sayings and answering hard questions, were seen to be in him, even in Daniel (named Belteshazzar by the king): now let Daniel be sent for, and he will make clear the sense of the writing.

And I have had news of you, that you have the power of making things clear, and of answering hard questions: now if you are able to make out the writing and give me the sense of it, you will be clothed in purple and have a gold chain round your neck and be a ruler of high authority in the kingdom.
