Jon'adab a shortened form of the name Jehonadab, for which it is used indifferently in the Hebrew as applied to either of two men in certain passages; but these have not been accurately represented in the A.V. which applies the briefer form indeed to either, but the full form to but one in three of these passages. SEE JEHONADAB.
