Exodus 25:35

and a calyx of one piece with it under each pair of the six branches going out from the lampstand .

One bud shall be under the first pair of branches extending from the lampstand, a second bud under the second pair, and a third bud under the third pair—six branches in all.

And there shall be a knop under two branches of the same, and a knop under two branches of the same, and a knop under two branches of the same, according to the six branches that proceed out of the candlestick.
