In Parshat Tetzaveh (Exodus 27:20-21) the first mention of the term "ner tamid" in the Torah appears. I had always thought of the ner tamid as the "eternal" or "perpetual" light. Yet it is clearly stated in this passage that the ner tamid shall burn from evening to morning.
20 וְאַתָּ֞ה תְּצַוֶּ֣ה ׀ אֶת־בְּנֵ֣י יִשְׂרָאֵ֗ל וְיִקְח֨וּ אֵלֶ֜יךָ שֶׁ֣מֶן זַ֥יִת זָ֛ךְ כָּתִ֖ית לַמָּא֑וֹר לְהַעֲלֹ֥ת נֵ֖ר תָּמִֽיד׃
You shall further instruct the Israelites to bring you clear oil of beaten olives for lighting, for kindling lamps regularly.
21 בְּאֹ֣הֶל מוֹעֵד֩ מִח֨וּץ לַפָּרֹ֜כֶת אֲשֶׁ֣ר עַל־הָעֵדֻ֗ת יַעֲרֹךְ֩ אֹת֨וֹ אַהֲרֹ֧ן וּבָנָ֛יו מֵעֶ֥רֶב עַד־בֹּ֖קֶר לִפְנֵ֣י יְהוָ֑ה חֻקַּ֤ת עוֹלָם֙ לְדֹ֣רֹתָ֔ם מֵאֵ֖ת בְּנֵ֥י יִשְׂרָאֵֽל׃ (ס)
Aaron and his sons shall set them up in the Tent of Meeting, outside the curtain which is over [the Ark of] the Pact, [to burn] from evening to morning before the LORD. It shall be a due from the Israelites for all time, throughout the ages.
In the synagogues I've attended the light is kept on perpetually.
- If "ner tamid" does not mean perpetual or eternal light, what is the correct translation?
- When did this change in keeping the light on from evening to morning to perpetually occur?
- Was there some event or reason for the change?
