Pillars - The Hebrew word signifies ordinarily a “prop” (margin). It is generally supposed to mean in this place a “railing,” or “balustrade,” a sense which connects and harmonises the present passage with the parallel passage in Chronicles (marginal reference), where Solomon is said to have made of the almug-wood “stairs” for the temple and for his own house.
Harps - The Jewish harp כנור kı̂nnôr was of a triangular shape, and had ordinarily ten strings. It probably resembled the more ancient harp of the Assyrians, which was played with a plectrum, as was (ordinarily) the “kinnor.”
Psalteries - The psaltery, or viol. Hebrew: נבל nebel; Greek: νάβλα nabla, was a stringed instrument played with the hand; perhaps a lyre, like those on Hebrew coins, the sounding-board of which is shaped like a jug; or, perhaps, a sort of guitar, with a hollow jug-shaped body at the lower end.
