A Lamp Kept Burning
Exodus 27:20-21
20 “You shall command the children of Israel, that they bring to you pure olive oil beaten for the light, to cause a lamp to burn continually. · WEB
The nation supplies the oil and the priests tend the flame, and neither the light nor its keeping is automatic.
You shall command the children of Israel, that they bring to you pure olive oil beaten for the light, to cause a lamp to burn continually Exodus 27:20.
Two verses, set apart from the construction details around them, and they concern maintenance rather than building. The lampstand has been specified in gold; here the arrangement for keeping it alight is given, and it involves the whole nation.
The oil is pure olive oil beaten for the light. Beaten, not pressed — the first oil, obtained by crushing the olives by hand rather than by loading a press, which yields the clearest oil and the least of it. It burns without smoke, and it costs the most per measure of anything the sanctuary consumed daily.
The supply is continual and so is the obligation. This is not a one-time contribution toward a building project; it is a standing requirement on every household, renewed as long as the lamp burns, and it means the light in the holy place is fed by a nation that never sees it. Israel would carry oil across a desert for forty years to illuminate a room they were not permitted to enter.
In the Tent of Meeting, outside the veil which is before the covenant, Aaron and his sons shall keep it in order from evening to morning before Yahweh Exodus 27:21.
The tending is the priests' work and it is done at night. Wicks are trimmed, ash is removed, oil is replenished, and the room is the only place in the camp where anything is happening while the nation sleeps. A lamp described as burning continually is in fact burning because someone is awake with it.
That combination is the substance of these two verses. Something is called perpetual, and it is sustained by a daily supply and a nightly attendance, neither of which can be skipped without the perpetual thing going out.
It shall be a statute forever throughout their generations on the behalf of the children of Israel Exodus 27:21.
On their behalf. The priests are not doing this for themselves, and the phrase is the first appearance of a principle the next two chapters develop at length: everything done inside the tent is done in the name of people who are standing outside it.
