And there are two olive trees alongside it, one on the right side of the bowl and one on its left side.’”​—Zechariah 4:1-3.

5. How were the seven lamps furnished with illuminating fuel from a central reservoir, and how was this central supply kept full?

⁵ The seven lamps had a central supply of illuminating oil. It was that bowl on the top of the golden lampstand, from which bowl there extended seven pipes, an individual pipe running to each individual lamp to convey oil to it from the central supply. But from where did this bowl get its supply of oil, and how regularly? From those two olive trees that stood alongside the bowl, one tree to its right and the other tree to its left. Those trees could be a constant source of supply, and they were immediately at hand, with no need for transporting oil from afar.
