Here Barzillai means that he is old and that there is no reason for him to accompany David. This rhetorical question can be translated as a statement. Alternate translation: "I am certainly not going to live many more years. There is no good reason for me to go up with the king to Jerusalem." (See: rc://en/ta/man/translate/figs-rquestion)
