a light-source: the thing that gives off light, such as a luminary in the sky or a lamp
This word names the source or carrier of light, not light itself. Its near relative אוֹר is the glow, the brightness that fills a room or a sky; מָאוֹר is the object that produces that glow. The word is built to mean roughly "a light-maker," the same way Hebrew forms words for a key ("what opens") or an altar ("the place of slaughter").
The three settings where it appears are the same idea aimed at different objects.
- In the sky it names the great bodies that light the day and night
- in the worship tent it names the lamp that has to be kept burning and the oil poured into it
- in poetry it can be turned on a face or a pair of eyes that shine
The lamp and the luminary are not two meanings but one: a thing that radiates light, scaled from a sun down to a flame, and then stretched figuratively to a glowing face.
The writers of the early books seem to have chosen this word on purpose to tie the heavens to the sanctuary. The same rare term that names the sun and moon in the creation account names the lamp oil in the tabernacle, so that the seven-branched lampstand quietly echoes the lights God hung in the sky. Reading the word across its handful of appearances, that link between the cosmos and the worship tent is the most striking thing about it.

What מָאוֹר means in the tabernacle texts, where it appears in phrases like "oil for the light" and "the lampstand of the light."
- majorityAn abstract noun, "light" or "light-source"; the phrase "the lampstand of the light" is then "the shining lampstand," reading the word as describing a quality.; Cornelis Houtman and Raymond de Hoop, "מָאוֹר - light (source)," Semantics of Ancient Hebrew Database, 2011/2019
- minorityA verbal noun meaning "lighting," so the phrases read "oil for the lighting" and "the lampstand for lighting," avoiding the awkward "lampstand of the lamp."; Jacob Milgrom, Leviticus 23-27 (AB 3B, Doubleday, 2001), on Lev 24:2
- minorityA concrete "luminary" or lamp apparatus, deliberately the same word used for the heavenly lights of the creation account.; William H. C. Propp, Exodus 19-40 (AB 2A, Doubleday, 2006), on 25:6 and 27:20
