Nave.' (Hebrew, 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, That Is, 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.
