(Heb. gao ), anything convex or arched, as the boss of a shield, ( Job 15:26 ) the eyebrows, ( Leviticus 14:9 ) an eminent place. ( Ezekiel 16:31 ) It is rendered once only in the plural, "naves," ( 1 Kings 7:33 ) meaning the centres of the wheels in which the spokes are inserted i.e. the hubs. In ( Ezekiel 1:18 ) it is rendered twice "rings," and margin "strakes," an old word apparently used for the nave (hub) of a wheel and also more probably for the felloe or the tire, as making the streak or stroke upon the ground.
