出埃及記27:20-21

27:20 「你要吩咐以色列人，把那為點燈搗成的清橄欖油拿來給你，使燈常常點著。
27:21 在會幕中法櫃前的幔外，亞倫和他的兒子，從晚上到早晨，要在耶和華面前經理這燈。這要作以色列人世世代代永遠的定例。」

   ²⁰ “Command the Israelites to bring you clear oil of pressed olives for the light so that the lamps may be kept burning. ²¹ In the tent of meeting, outside the curtain that shields the ark of the covenant law, Aaron and his sons are to keep the lamps burning before the Lord from evening till morning. This is to be a lasting ordinance among the Israelites for the generations to come.

    上帝在這裡啟示摩西，要使用清橄欖油點燈，並且要整天讓燈都亮著，這是很重要的，讓人感受到上帝的光明永不改變！
