אַחְמְתָא

Based on the provided lexicon data, the word "אַחְמְתָא" (ach.me.ta), also known as Ecbatana, appears to be a proper name referring to a person. However, given the limited occurrences and the definition of Ecbatana, it is more likely that "אַחְמְתָא" is the Hebrew name of a person from Ecbatana. Since the semantic domain is labeled as "Proper Name: Person" and there is only one occurrence in the entire Bible, it suggests that this word is a personal name and not the name of a place. Therefore, when we see "אַחְמְתָא" in the Bible, it refers to a specific individual from Ecbatana, possibly someone notable or influential in their time. The significance of "אַחְמְתָא" lies in its association with the city of Ecbatana, which was likely an important center for politics and culture in the ancient world. As a personal name, it provides insight into the geographic and cultural background of the individual and their family.
