Exodus 37:21-23

New King James Version

²¹ There was a knob under the first two branches of the same, a knob under the second two branches of the same, and a knob under the third two branches of the same, according to the six branches extending from it. ²² Their knobs and their branches were of one piece; all of it was one hammered piece of pure gold. ²³ And he made its seven lamps, its ^(A)wick-trimmers, and its trays of pure gold.
