For he was wiser than all men; than Ethan the Ezrahite, and Heman, and Chalcol, and Darda, the sons of Mahol: and his fame was in all nations round about. (1 Kings 4:31)
Some of Solomon’s rivals in wisdom are known only from this passage. Some think Heman and Ethan are the tabernacle musicians appointed by David (1 Chron. 6:33, 44), who may also be the Ezrahites in the titles of Ps. 88 and 89. A “Heman” is designated as “the king’s seer in the words of God” (1 Chron. 25:5).
However, the identity of these names is not definitely established.
