Jashen
JASHEN (jā’shĕn, brilliant). Father of some of David’s heroes (2Sam.23.32). Confusion arises from the fact that 1Chr.11.33-1Chr.11.34 calls him Hashem, the Gizonite (evidently another spelling); the LXX there has “the Gunite.”
JASHEN jā’ shən (יָשֵׁ֖ן). One member of the thirty “mighty men” of David. The Heb. text of 2 Samuel 23:32 reads “the sons of Jashen,” whereas the parallel passage in 1 Chronicles 11:34 (KJV) has “the sons of Hashem the Gizonite.” It is clear that “sons of” is a dittography of the last three consonants of the previous word (שַׁעַלְבֹנִֽי). The original reading must have ben either “Jashen (or Hashem) the Gizonite.”
International Standard Bible Encyclopedia (1915)
ja’-shen, jash’-en (yashen, "asleep"(?)): Seemingly the father of some of David s thirty valiant men (2Sa 23:32 f). The Massoretic Text reads "Eliahba the Shaalbonite, the sons of Jashen, Jonathan, Shammah the Hararite, .... " 1Ch 11:33 f has Eliahba the Shaalbonite, the sons of Hashem the Gizonite, Jonathan the son of Shagee the Hararite .... " It is clear that "sons of" are a dittography of the last three consonants of the previous word. Septuagint, Lucian in 2 Samuel and 1 Chronicles has ho Gouni, "the Gunite," for "the Gizonite," perhaps correctly (compare Ge 46:24; Nu 26:48 for "Guni," "Gunite"). So 2Sa 23:32 may be corrected thus: "Eliahba the Shaalbonite, Jashen the Gunite, Jonathan the son of Shammah the Hararite." Jashen then becomes one of the thirty = "Hashem" of 1Ch 11:34.
