John Gill Commentary Exodus 25:36

"Their knops and their branches shall be of one piece with it; the whole of it one beaten work of pure gold." — Exodus 25:36 (ASV)

Their knops and their branches shall be of the same
Of the same metal, gold, and of same mass:

all of it shall be one beaten work of pure gold
not made in parts, and then put and soldered together, but the whole candlestick in all its parts and branches were to be beaten out of one piece of gold.
