1Ki 7:37-38 “Thus he made the ten stools of one kind of casting, measure, and form, and also ten brazen basins (כּיּרות), each holding forty baths, and each basin four cubits.” In a round vessel this can only be understood of the diameter, not of the height or depth, as the basins were set upon (על) the stands. על־המּכונה אחד כּיּור is dependent upon ויּעשׂ: he made ten basins, ... one basin upon a stand for the ten stands, i.e., one basin for each stand. If then the basins were a cubit in diameter at the top, and therefore their size corresponded almost exactly to the length and breadth of the stand, whilst the crown-like neck, into which they were inserted, was only a cubit and a half in diameter (1Ki 7:31), their shape must have resembled that of widespreading shells. And the form thus given to them required the shoulder-pieces described in 1Ki 7:30 and 1Ki 7:34 as supports beneath the outer rim of the basins, to prevent their upsetting when the carriage was wheeled about.
