'Excluded' in the Bible

When the tabernacle is to go forward, the Levites shall take it down; and when the tabernacle is to [be set up for] camp, the Levites shall set it up. But the layman (non-Levite) who approaches the tabernacle shall be put to death.

So you shall appoint Aaron and his sons, and they shall observe and attend to their priesthood; but the layman (non-Levite) who approaches [the holy things] shall be put to death.”

Now those to camp before the tabernacle toward the east, before the Tent of Meeting, toward the sunrise, were to be Moses, and Aaron and his sons, performing the duties of the sanctuary for whatever was required of the Israelites; and the layman (non-Levite) who approached [the sanctuary] was to be put to death.

and said to him, “We are unclean because of a human corpse. Why should we be excluded from presenting the Lord’s offering at its appointed time with the other Israelites?”
