Numbers 4:20 in the King James Version of the Bible reads, "But they shall not go in to see when the holy things are covered, lest they die." This verse is part of a larger passage in the book of Numbers that describes the responsibilities of the Kohathites, one of the three Levitical families responsible for the care and transportation of the Tabernacle and its sacred objects.

The context of this verse is important for understanding its meaning and significance. The Kohathites were charged with the sacred task of carrying the most holy items of the Tabernacle, including the ark of the covenant, the table of showbread, the golden altar, and the utensils used in the Tabernacle's service. These objects were considered so holy that only the priests, and specifically the high priest, were allowed to handle them. The Kohathite clan was tasked with carefully wrapping and covering these items so that they would not be seen by anyone who was not authorized to do so.

The verse itself serves as a warning to the Kohathites, instructing them not to look upon the holy things when they are covered. The consequence for disobeying this command is severe: death. This underscores the seriousness and sanctity of the items they were transporting and the need for the Kohathites to fulfill their duties with the utmost reverence and care.

The themes present in Numbers 4:20 are those of holiness, obedience, and the fear of the Lord. The holiness of the items themselves is emphasized by the strict prohibition on looking at them when they are covered. This serves as a reminder of the need for reverence and respect in dealing with sacred things. The obedience required of the Kohathites is evident in the command not to look at the holy things, regardless of their curiosity or interest. The consequences of disobedience are clear, highlighting the seriousness of following God's commands. The fear of the Lord is also evident in this verse, as the possibility of death serves as a stark reminder of the power and holiness of God.

In addition to these themes, there is also a symbolic significance to the covering of the holy things. The act of covering these sacred items represents not only their protection and preservation but also their separation from the ordinary. By keeping them concealed, they are set apart as special and reserved for the worship and service of God alone.

This verse can also be understood in a broader theological context. It reflects the belief in the Old Testament that the presence of God was uniquely and tangibly manifested in specific objects and places, such as the ark of the covenant or the Tabernacle itself. As a result, there were strict protocols and regulations surrounding these sacred items, emphasizing the need for purity, reverence, and obedience in their handling and care.

Ultimately, Numbers 4:20 serves as a poignant reminder of the holiness and power of God, as well as the importance of obedience and reverence in approaching the sacred. It also serves as a warning against the casual or irreverent handling of holy things. This verse challenges readers to consider the way they approach and handle the things of God, and to recognize the significance of His presence and holiness.
