Son_1:17, "rafters (galleries margin) of fir"; the crossbeams, the carved ceiling, fretted work: rachit. The Qeri, or Hebrew margin, has rahit, an ambulatory; not probable. In Son_7:5 translated "the king is held bound with the flowing ringlets"; compare Son_6:5. In Eze_41:15; Eze_42:3, "the galleries" are terrace buildings. Smith's Bible Dictionary identifies the" pillars" and "galleries," Eze_42:3; Eze_42:5-6; "the reason of the upper chambers being shorter is ascribed to the absence of supporting pillars which allowed an extra length to the chambers of the lower story; the space included within the pillars would form an open gallery."
