Gizonite
GIZONITE (gĭ'zō-nīt). Hashem, one of David’s valiant men, was described as a Gizonite (1Chr.11.34). Probably an error for Gunite. He was probably the same as Jashen the Gunite (2Sam.23.32).
GIZONITE gī’ zə nīt (Heb. גִּ֣זוֹנִ֔י), appears only in a list of David’s mighty warriors (1 Chron 11:34), a masculine gentilic derived from an ancient place-name. Traditionally understood as a patronymic, but more likely of Old Canaanite origin. Location presently unknown; however, the man described by the term Gizonite is stated in 2 Samuel 23:32 to have been, in fact, the son of Jashen which makes the geographical ascription of Gizon more certain.
International Standard Bible Encyclopedia (1915)
gi’-zon-it: This gentilic name in 1Ch 11:34, "Hashem the Gizonite," is probably an error for "Gunite" (compare Nu 26:48), and the passage should be corrected, after 2Sa 23:32, into "Jashen the Gunite."
