At its core this word names effective power, the capacity someone or something has to act, to endure, and to prevail. It is the strength a soldier carries into battle, the surge of energy in a strong man, the force of an army on the march, and the God-given might that makes a person or nation stand firm.

The major lexica converge on a single underlying notion: effective capacity or potency, the power to get something done. HALOT (Koehler-Baumgartner) lists capacity or power first; TDOT's article (H. Eising) traces all the senses to a primitive meaning of standing firm and steady, as a soldier does in battle. DCH (Clines) argues on methodological grounds that no one sense should be privileged as primary, but all analysts agree these senses cluster around the same concept of realized power.

This is the root sense from which the word's other senses grow. An army is strength gathered into a body of fighters. Wealth is strength stored up in resources. Worth is strength of character. Each is a way of asking the same question: what power does this person, or this thing, actually have?

When strength is gathered into a body of soldiers, this word names the army itself. It is Pharaoh's force drowned in the sea, the troops a king musters, the host that marches out to war. English Bibles call it the host, the army, or simply the forces.

The word can mean the whole army of a nation or a single contingent within it, and in the plural it means armies or bands of troops. Jeremiah uses it dozens of times for the Babylonian army encircling Jerusalem. Chronicles and Daniel use it for the great forces of the Persian period. The military sense is by far the most frequent in the corpus: Chronicles alone supplies well over a hundred occurrences.

The link to the strength sense is direct: an army is a kingdom's power made visible, the means by which it imposes its will. Eising's sociological observation is relevant here: in early Israel the warrior class and the propertied class were largely the same people, which is why army, wealth, and worth shade into each other so naturally.

Strength also takes the form of what a person owns. Here the word means wealth, the goods, livestock, money, and property that make up someone's resources. It is the plunder carried off from a captured city, the riches a self-made man boasts of, the substance a nation hopes to draw on.

The Bible often uses this sense as a warning. People say their own power and the might of their hand have gotten them their wealth, forgetting that the strength to get it was given to them by God (Deut 8:17-18). Wealth gained through oppression does not last, and the substance a person trusts in can vanish in a moment. The sense stays close to the root: wealth is strength stored up, power a person hopes to draw on when needed.

The connection between military conquest and wealth is direct in several passages: armies plunder cities, and the spoils become someone's resources. Eising (TDOT) explains this sociological link: in early Israel, the warrior class and the propertied class were largely the same group, so the word that named a soldier's fighting capacity naturally extended to the resources that capacity had won and maintained.

Applied to a person's character and standing, the word names worth, the inner and social strength that makes someone capable, dependable, and admirable. The standard phrase is a man of this quality, applied in the Deuteronomistic History to Gideon, Jephthah, Kish, David, Naaman, and Jeroboam. In every case it names a person whose strength shows in who they are and what they can do, not merely in their muscles.

The scope is wide. The capable men Jethro recommends as judges in Exodus 18 are אַנְשֵׁי חַיִל: men of ability and trustworthiness suitable for administration. The chronicles extend the epithet beyond warriors to Levites, gatekeepers, and priests who are capable for the work of the temple. Ruth is called a woman of this quality in Ruth 3:11, matching the introduction of Boaz in 2:1 as a man of this quality. The parallel is deliberate and recognized by virtually all modern Ruth commentators.

The sense often carries a note of bravery, the valor that makes a good soldier, but it is broader than courage. It can mean ability, capability, or moral excellence in any sphere. Scholarship has largely moved away from the KJV rendering virtuous woman and toward translations that preserve the strength and capability register: woman of valor (Alter, JPS) or woman of strength (Fox, NRSVue 2022). The decisive argument is structural: the masculine version of the phrase is the title for a warrior, and the feminine version cannot be emptied of that force simply because it is applied to a woman in a household context.
