Leprosy
Leprosy in this context is a physical manifestation of God's judgment on King Uzziah for his pride and disobedience in attempting to burn incense in the temple, a duty reserved for priests.
Leprosy symbolizes sin and impurity, highlighting the consequences of pride and the importance of obedience to God's commands. It serves as a reminder of the holiness required to approach God.
In ancient Israel, leprosy was seen as a severe impurity, leading to social and religious isolation. It was often viewed as a divine punishment.
