Counter-Arguments

The strongest case that this verse does not belong in this theme.

Christ as High Priest

This verse describes Phinehas, a human priest, participating in a military action with specific ritual objects, which is a literal historical event within the Levitical system and does not mention or allude to a future, transcendent high priest or sacrifice.
