He made also posts of threescore cubits,.... Jerom thinks, that between the outward wall which surrounded this building, and the building itself, these posts or pillars were placed for ornament, which took up the space of sixty cubits; but rather these design the posts or columns of the gate, which supported the arch over it, on which were rooms or stories, and these were sixty cubits high; for of their height is this measure to be understood.
So the Targum,"and he made posts, sixty cubits was their height;''in the Targum, in the Polyglot Bible by Montanus, it is,"and he made sixty posts, their height a cubit:''and to this agree Jarchi and Kimchi; these were thirty five yards high, the height of the temple ordered to be built by Cyrus, Ezr 6:3.
