Numbers 4:20 Meaning and Commentary

Numbers 4:20

But they shall not go in to see when the holy things are
covered
They were not to be present while they were packing up, test they should see any of them with their eyes; they were not to go in until they were quite covered out of sight; which may signify the hiding of the mysteries of grace in those things under the former dispensation, when even the Levites themselves were not admitted to a sight of them; see ( Ephesians 3:4 Ephesians 3:5 ) ;

lest they die;
by the immediate hand of God.

20 But the men of Kohath must not go in and look at the holy things. They must not look at them even for a moment. If they do, they will die."

22 "Count the Gershon families. Make a list of them family by family.
