HACHMONI

Father of Jehiel
And this is the number of the mighty men whom David had; Jashobeam, an Hachmonite, the chief of the captains: he lifted up his spear against three hundred slain by him at one time. (1 Chronicles 11:11)
Also Jonathan David's uncle was a counsellor, a wise man, and a scribe: and Jehiel the son of Hachmoni was with the king's sons: (1 Chronicles 27:32)
