νουμηνία

Based on the given data, the Greek word νουμηνία (noumēnia) refers to a 'New Moon'. This term is tied to the concept of tracking time according to lunar cycles. The fact that it appears only once in the Bible suggests that it is not a common or central theme in scripture. Given its translation as 'New Moon', it is likely that this word was used to specify dates or appointments in relation to the lunar cycle. This would imply its use in a calendrical or scheduling context, possibly used to organize festivals, rituals, or significant events. The sole occurrence of this word in the Bible is significant in itself, implying that its usage is either unique to this passage or rare within the broader scope of scripture. Without further context, it is difficult to assess the full significance of this term; however, its connection to a specific date and a distinct astronomical event suggests that it is an important part of the author's narrative.
