What does the Bible say about the purity and holiness of God?

In Numbers chapter five, we see a clear representation of God's holiness and the seriousness of dealing with sin. God's glory is inherently linked with His purity, as stated when Moses sought to see His glory. God explained that no man could see His face and live because of sin's presence. This signifies that, in order to be accepted by God, we must be seen as perfect and pure. The text outlines that sin, represented by leprosy, the issue of blood, and defilement from the dead, inherently corrupts us. Thus, God's holiness necessitates separation from such corruption to maintain justice and holiness.
