Barzillai in Wikipedia
the Gileadite of Rogelim was 80 years old at the time of
Absalom's revolt against King David. Barzillai supplied
provisions for David's army at Mahanaim (2 Samuel 17:27-29).
After the death of Absalom, Barzillai, being an old man, was
unable to accompany the king back to Jerusalem, but brought
Chimham to David for the return journey (2 Samuel 19:31-37).
