'Knobs' in the Bible

“You shall make a lampstand of pure gold. The lampstand and its base and its shaft shall be made of hammered work; its cups, its calyxes and its flowers shall be all of one piece with it.

and in the [center shaft of the] lampstand [you shall make] four cups shaped like almond blossoms, with their calyxes and their flowers.

Their calyxes and their branches shall be of one piece with it; all of it shall be one piece of hammered work of pure gold.

Then he made the lampstand (menorah) of pure gold. He made the lampstand of hammered work, its base and its [center] shaft; its cups, its calyxes, and its flowers were all of one piece with it.

On the center shaft of the lampstand there were four cups shaped like almond blossoms, with calyxes and flowers [one at the top];

Their calyxes and their branches were of one piece with it; all of it was a single hammered work of pure gold.
