Why was the Ark carried by priests and not touched directly?
Answered in 1 source
The Ark symbolized holiness, necessitating that only priests carry it using staves.
The Ark of the Covenant was carried by priests using staves to emphasize its holiness and the sacredness of God’s presence among His people. Exodus 25:14 specifies that these staves were to remain in the rings of the Ark, as no one was allowed to touch it directly. This indicates the reverence required for approaching God. In a New Covenant understanding, it reflects how believers are now priests who proclaim the gospel of Christ but must do so with respect and acknowledgement of His holiness. It also symbolizes the careful manner in which God's presence is to be treated, pointing to the seriousness of the relationship between God and humanity.
