Charles Ellicott Commentary Exodus 25:34

"and in the candlestick four cups made like almond-blossoms, the knops thereof, and the flowers thereof;" — Exodus 25:34 (ASV)

In the candlestick. —By “the candlestick” in this place must be understood as the central shaft or stem, which is viewed as that to which all the rest is accessory. Here the triple series was to be repeated four times.
