And of the children of the priests
 Who could not make out their pedigree, for those that could are mentioned before: 
 the children of Habaiah, the children of Koz, the children of
 Barzillai;
 how the latter came by this name follows: 
 which took a wife of the daughters of Barzillai the Gileadite, and was
 called after their name;
 this man married a woman that descended from the famous Barzillai the Gileadite, in the times of David; and the priesthood being in disuse, and mean and despicable, in Babylon, he chose to take the name of his wife's family, and pass for a descendant from that, and perhaps destroyed, or at least neglected, to take care of the genealogy of his own family.
