Bilangan 18:3

Namun ketika melakukan tugas mereka, mereka tidak boleh mendekati mezbah maupun barang-barang kudus di kemah-Ku. Jika mereka mendekatinya, mereka dan kalian juga akan mati.

And they shall keep thy charge, and the charge of all the tabernacle: only they shall not come nigh the vessels of the sanctuary and the altar, that neither they, nor ye also, die.
