Jamieson, Fausset & Brown, on 1Chr 2:6

“And the sons also of Zare: Zamri, and Ethan, and Eman, and Chalchal, and Dara, five in all.”

“Zimri, and Ethan, and Heman, and Calcol, and Dara--These five are here stated to be the sons of Zerah, that is, of Ezra, whence they were called Ezrahites (Kg1 4:31). In that passage they are called "the sons of Mahol," which, however, is to be taken not as a proper name, but appellatively for "sons of music, dancing," &c. The traditional fame of their great sagacity and acquirements had descended to the time of Solomon and formed a standard of comparison for showing the superior wisdom of that monarch. Jewish writers say that they were looked up to as prophets by their countrymen during the abode in Egypt.”
