When David came to Mahanaim, Shobi the son of Nahash from Rabbah of the Ammonites, Makir the son of Ammiel from Lo Debar, and Barzillai the Gileadite from Rogelim

Now when Barzillai the Gileadite had come down from Rogelim, he crossed the Jordan with the king so he could send him on his way from there. ¹ 

But Barzillai was very old – eighty years old, in fact – and he had taken care of the king when he stayed in Mahanaim, for he was a very rich ¹  man.
