Counter-Arguments

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

This verse describes David asking a human Levitical priest to bring him a ritual garment (the ephod) for consultation, which is a direct action within the Old Testament priestly system, not a foreshadowing or fulfillment of Christ's high priesthood.
