Rashi on Tetzaveh 30:7

English: בהטיבו WHEN HE TRIMMETH — This word is an expression for cleansing the bowls of the candelabrum from the ashes of the wicks which had burnt out during the night; and he used to clean them (the lamps) out every morning. הנרת THE LAMPS — luces in old French And this is the meaning of נרות whenever it is mentioned in connection with the candelabrum, except in any passage where the term העלאה “causing to ascend” (any verbal form which is the Hiphil of עלה), which denotes lighting is used, and there it signifies “lights”, (The translation here is therefore: “when he cleans out the lamps”, not “when he trims the lights”).
