A BOWL — specifically the reservoir bowl set atop Zechariah's vision-lampstand, feeding oil down through pipes to its seven lamps (4:2-3) — a gravity-fed design with no human hand shown refilling it, unlike the tabernacle menorah of Exodus 25 (not yet on these pages), which the priests topped up by hand every evening. The same root elsewhere names a natural spring or basin (Achsah's request for gullot mayim, 'springs of water,' Joshua 15:19) — the image throughout is a self-replenishing source, not a static container. → first discussed at Zechariah 4:2
