Numbers 4:20

20 Other men see not by any curiosity those things that be in the saintuary, before that those be wrapped; else they shall die. (And let not other people who be curious see those things that be in the sanctuary, before that they be wrapped up; for if they do, then they shall die/then they must be put to death.)

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.

Numbers 4:20 In-Context

18 Do not ye lose, or destroy, the people of Kohath from the midst of the Levites; (Do not ye allow the people of Kohath to be done away from the midst of the Levites;)

19 but do ye this thing to them, that they live, and die not, if they touch the holy of holy things. Aaron and his sons shall enter, and they shall dispose the works of all the sons of Kohath, and they shall part (to each) what who oughteth to bear. (but do ye this thing for them, so that they shall live, and not die, when they approach the most holy things. Aaron and his sons shall enter, and they shall direct the works of all the sons of Kohath, and they shall assign to each what he ought to carry.)

20 Other men see not by any curiosity those things that be in the saintuary, before that those be wrapped; else they shall die.

21 And the Lord spake to Moses, and said,

22 Take thou the sum, or the number, also of the sons of Gershon, by their houses, and families, and kindreds; (Take thou also the sum, or the number, of the sons of Gershon, by their houses, and families, and kindreds;)
