'Added' in the Bible

However, the king added, “He may return to his house, but he may not see my face.” So Absalom returned to his house, but he did not see the king.

He added, “If only someone would appoint me judge in the land. Then anyone who had a grievance or dispute could come to me, and I would make sure he received justice.”

I’m now 80 years old. Can I discern what is pleasant and what is not? Can your servant taste what he eats or drinks? Can I still hear the voice of male and female singers? Why should your servant be an added burden to my lord the king?
