Y Benaías hijo de Joiada era sobre los Ceretheos y Peletheos; y los hijos de David eran los príncipes cerca del rey.
Rashi on I Chronicles
over the Cherethites and the Pelethites The meaning is that they were nations, as it is written, (Zeph. 2:5): “Woe to... the nation of Cherethites,” and from their nations were mighty warriors with David, and Benaiah was over them. Another instance of this (II Sam. 15:18): “... and all his servants passed beside him, and all the Cherethites and all the Pelethites and all the Gittites.”
Rashi on I Chronicles
and the sons of David were first at the king’s hand The meaning is that David’s sons were always first beside the king to perform all his necessities.
