John Calvin Commentary Numbers 18:22

"And henceforth the children of Israel shall not come nigh the tent of meeting, lest they bear sin, and die." — Numbers 18:22 (ASV)

Neither must the children of Israel. He again emphasizes what he had previously said, that the Levites were chosen to attend to the sacred things, since God would not admit all the people indiscriminately, as before the giving of the Law, when others also offered the sacrifices. But, nevertheless, He strongly charges them that they should be attentive to the performance of their duties, since, if any of them should offend, their crime would be fatal. For this is how we must understand His words, they shall bear their iniquity²⁰² to die: just as in the next verse He says that they will be guilty of all the defilements, because if the service of God should be defiled through negligence, the crime will be imputed to them.

²⁰² See margin, A. V. He paraphrases the words of verse 23. He paraphrases the words of verse 23.
