Contradiction with Exodus 25:31
While Numbers 8:4 describes the candlestick as being of beaten gold according to the pattern, Exodus 25:31 also describes the menorah to be made with intricate details but does not mention beaten gold, creating a contrast in emphasis.
Exodus 25:31: And thou shalt make a candlestick [of] pure gold: [of] beaten work shall the candlestick be made: his shaft, and his branches, his bowls, his knops, and his flowers, shall be of the same.
