men, people: an old poetic word for a group of men or people, found almost only in the plural and mostly in set phrases
This is a rare, old-fashioned word for "men" or "people." It nearly always shows up in the plural, and by the time of the Hebrew Bible it survives mostly in poetry and in a few fixed phrases rather than as an everyday term. The ordinary, everyday word for a man was אִישׁ; this one had a more elevated, archaic ring, closer in feel to the poetic word for frail humanity (אֱנוֹשׁ).
Most often it simply means "people" or "men," and it usually leans on the word that follows it to fill out the picture: "men of falsehood" for liars, "men of my circle" for close friends, "men of my tent" for a household. In a couple of places it narrows to adult males as distinct from women and children, as when a captured town's "men, women, and little ones" are counted together.
Its single most common use is a frozen expression for a small group: "few in number," literally "men of a number," people few enough to be counted, or plainly "few men." Israel remembers itself this way, a mere handful before it grew into a nation, and is warned that disobedience could shrink it back to a countable few.
