2 Samuel 19:31-34 New King James Version (NKJV)

31. And Barzillai the Gileadite came down from Rogelim and went across the Jordan with the king, to escort him across the Jordan.

32. Now Barzillai was a very aged man, eighty years old. And he had provided the king with supplies while he stayed at Mahanaim, for he was a very rich man.

33. And the king said to Barzillai, “Come across with me, and I will provide for you while you are with me in Jerusalem.”

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