2 Samuel 19:32-36

Barzillai was very old: eighty years old; and he had provided the king food while he stayed in Mahanaim, for he was a very great man.

So the king said to Barzillai, “You cross over with me, and I will provide you food in Jerusalem with me.”

But Barzillai said to the king, “How long do I still have to live, that I should go up with the king to Jerusalem?

I am now eighty years old. Can I distinguish between good and bad? Or can your servant taste what I eat or what I drink? Or can I still hear the voice of men and women singing? Why then should your servant be an added burden to my lord the king?

Your servant would merely cross over the Jordan with the king. So why should the king compensate me with this reward?
