利未記 16:2

「要告訴你哥哥亞倫，不可隨時進聖所的幔子內、到櫃上的施恩座前，免得他死亡，因為我要從雲中顯現在施恩座上。

And the LORD said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the vail before the mercy seat, which is upon the ark; that he die not: for I will appear in the cloud upon the mercy seat.
