Matthew Poole and continuators on Zechariah 4:3

3 And two olive trees by it, one upon the right side of the bowl, and the other upon the left side thereof.

Some say Branches; better Trees, which well rooted, will continue, and perpetually supply the Bowls, and that will supply the Lamps.

Not more, or fewer than two.

So placed that the candlestick stood between them, and each Tree stood at distance from the candlestick, on the right, and left hand thereof; that they might distil their oil into the Basin or Bowl. All which is an Emblem of the Church, both what it is made of, pure Gold; what made for, to be light in the World; to shine as Lamps that continually burn, maintain'd with pure oil, distilled from the Olive Trees, not pressed out by man but continually, freely, and abundantly dropping or flowing from these olive Trees.
