🔼The name Sharar in the Bible
The name Sharar occurs only once in the Bible. Sharar the Ararite is the father of Ahiam, one of David's mighty-men (2 Samuel 23:33). In the parallel text of 1 Chronicles 11:35 there is no Ahiam son of Sharar the Ararite but there is an Ahiam son of Sacar the Hararite. Commentators generally deem these people to be the same.
🔼Etymology of the name Sharar
The name Sharar comes from the root שׁרר, which has to do with hardness or firmness:
For a meaning of the name Sharar, NOBSE Study Bible Name List reads Firm. Jones' Dictionary of Old Testament Proper Names follows the interpretation of Simonis (who proposed the Latin stabilimentum), and submits the entirely incomprehensible Hand, Stay and adds "i.e. of family," which doesn't help either. BDB Theological Dictionary does not offer an interpretation of the name Sharar but does list it under the root שׁרר.
