a lampstand: an upright stand made to hold oil lamps and lift their light off the ground
A lampstand is the fixture that holds the lamp, not the lamp itself. The word comes from the ordinary Hebrew word for a lamp, and it names the stand whose whole job is to raise a burning light where it can be seen. In an age before candles, the lamps it carried were small open dishes of olive oil with a floating wick.
Most of the time the word points to one famous object: the golden lampstand of Israel's worship. The book of Exodus describes it in loving detail, hammered from a single piece of pure gold, with branches shaped like almond blossoms and seven lamps burning across the top. It stood in the tabernacle, was tended morning and evening, and was later multiplied into the ten golden lampstands of Solomon's temple. When Babylon sacked Jerusalem, these were among the treasures carried off.
But the word is not locked to the sanctuary. It can name a plain piece of household furniture, such as the lampstand in the simple guest room built for the prophet Elisha, alongside a bed, a table, and a chair. And in one of Zechariah's visions the prophet is shown an all-golden lampstand as a picture with a deeper meaning, a sign of God's presence and provision for his people.
