FW-H6635 (army)
צָבָא(ṣāḇā)
A root, the verb ṣᵊḇā (H6633), is less prevalent than ṣāḇā, the noun form. It is often rendered as the archaic “host” after the KJV popularized it, and another common English translation is “army.” But this creates some issues with consistency. Clarity might be found in the fact that between ṣᵊḇā and ṣāḇā in Strong’s Concordance is ṣᵊḇâ (H6634), a verb that means to call forth or desire. A few dictionaries suggest “serve/servant,” but it may be best to think of it as “assemble/assembly.”
Occurrences
The first occurrence describes “the heavens and the earth, and all their ṣāḇā.” (Gen.2:1) Another, with the verb, is applied to “the ṣᵊḇā women who ṣᵊḇā at the entrance to the tent of meeting.” (Ex.38:8) The verb only appears in twelve verses, but the noun occurs almost 500 times in the Hebrew Scriptures. Numbers uses it more than 50 times, many in reference to the Israelite clans and their organization. Another concentration can be found in the prophetic literature, Isaiah and Zechariah in particular. In Joshua, despite what is considered a military campaign, the word appears just five times. Some noteworthy examples include:
Exodus 12:17 And you shall observe the Feast of Unleavened Bread, for on this very day I brought your ṣāḇā out of the land of Egypt.
Numbers 8:24 This applies to the Levites: from twenty-five years old and upward they shall ṣᵊḇā in the service of the tent of meeting.
Deuteronomy 24:5 When a man is newly married, he shall not go out with the ṣāḇā or be liable for any other public duty.
Conclusion
Some translators go so far as to render ṣāḇā as “war,” but this is not borne out by the text, which reserves milḥāmâ for that purpose. (see FW-H4421) The word denotes, rather, the act of assembling, whether for war, civil service, census, or other civic duties. The modern “All Volunteer Force” is a historical anomaly, and armies have usually been little more than the sum total of those citizens eligible for service.
