a belt or sash tied around the waist, ranging from a makeshift covering to a soldier's gear to a woman's fine accessory.
This word shows up in the Hebrew Bible in two closely related spellings, one grammatically masculine and one feminine, both built on the everyday verb for tying something around the waist. The standard dictionaries do not treat these as two different words with two different meanings; they are simply the two noun forms of one item, a belt or sash, and this entry covers both.
What changes from verse to verse is not the word's meaning but the setting. In Eden it is a hurried covering tied from leaves. On David's battlefield it is a reward a commander offers a soldier, a badge of honor rather than ordinary equipment. Elsewhere it is the plain belt a fighting man wears, the very thing that holds his sword, and it even shows up inside a set phrase meaning simply "of age to fight." In Isaiah it is a fine sash that marks a wealthy woman's dress, and in Proverbs it is a belt made for sale, a piece of merchandise a skilled woman produces and trades. One ordinary object, used in a wide range of situations.
The wider Semitic evidence backs this up. The root behind the word most likely meant something like "to enclose" or "to restrict" quite broadly across the family of related languages, and only in Hebrew and its close neighbor Aramaic did it settle down to mean specifically "to gird the waist." Akkadian, a more distant relative, used a completely different word for a belt, which tells us this particular sense developed locally rather than being inherited from a shared ancestor language.
