captain of fifty - not only captains of thousands, and centurions of a hundred, but even semi-centurions of fifty, shall fail.
honourable - literally, “of dignified aspect.”
cunning - skilful. The mechanic’s business will come to a standstill in the siege and subsequent desolation of the state; artisans are no mean “stay” among a nation’s safeguards.
eloquent orator - rather, as Vulgate, “skilled in whispering,” that is, incantation (Psa 58:5). See Isa 8:19, below; and on “prudent,” see on Isa 3:2.
