'Knobs' in the Bible

And thou shalt make a lamp-stand of pure gold; of beaten work shall the lamp-stand be made: its base and its shaft, its cups, its knobs, and its flowers shall be of the same.

And in the lamp-stand four cups shaped like almonds, its knobs and its flowers;

Their knobs and their branches shall be of itself all of one beaten work of pure gold.

And he made the candlestick of pure gold; of beaten work he made the candlestick: its base, and its shaft, its cups, its knobs, and its flowers were of itself.

And in the candlestick were four cups, shaped like almonds, its knobs, and its flowers;

Their knobs and their branches were of itself all of one beaten work of pure gold.
