גִּלְגָּל

Based on the provided data, the Hebrew word גִּלְגָּל (gil.gal) refers to a "wheel." This meaning is its core semantic definition, indicating a circular or rotating object, quite possibly a circular structure or device used for various purposes. Given the limited occurrences of this word in the Bible (once), its scope of usage appears to be very narrow. The fact that it's listed in the semantic domain of "Proper Name: Person" might suggest that it serves as a unique name, possibly belonging to an individual, rather than a general term in biblical language. However, the given definition does not provide further clarification on this usage. Since only one occurrence is documented, its significance and application within biblical contexts cannot be fully established. Nonetheless, as a singular name or proper noun, gil.gal remains an enigmatic figure tied to a specific, likely significant role in the narrative, waiting to be fully contextualized through further research and analysis.
