Joshua 22:31

And Phinehas the son of Eleazar the priest said unto the children of Reuben, and to the children of Gad, and to the children of Manasseh, This day we perceive that the Lord is among us, because ye have not committed this trespass against the Lord: now ye have delivered the children of Israel out of the hand of the Lord.
29

God forbid that we should rebel against the Lord, and turn this day from following the Lord, to build an altar for burnt offerings, for meat offerings, or for sacrifices, beside the altar of the Lord our God that is before his tabernacle.

30

And when Phinehas the priest, and the princes of the congregation and heads of the thousands of Israel which were with him, heard the words that the children of Reuben and the children of Gad and the children of Manasseh spake, it pleased them.

31

And Phinehas the son of Eleazar the priest said unto the children of Reuben, and to the children of Gad, and to the children of Manasseh, This day we perceive that the Lord is among us, because ye have not committed this trespass against the Lord: now ye have delivered the children of Israel out of the hand of the Lord.

32

And Phinehas the son of Eleazar the priest, and the princes, returned from the children of Reuben, and from the children of Gad, out of the land of Gilead, unto the land of Canaan, to the children of Israel, and brought them word again.

33

And the thing pleased the children of Israel; and the children of Israel blessed God, and did not intend to go up against them in battle, to destroy the land wherein the children of Reuben and Gad dwelt.

Counter-Arguments

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

Israel-Specific Promises

The verse describes Phinehas's perception of God's presence based on the tribes' actions, rather than explicitly stating a promise, prophecy, or covenant made to Israel.

Christ as High Priest

This verse describes an interaction involving Phinehas, a Levitical priest, and the tribes of Israel, focusing on their perceived faithfulness to the Lord. There is no mention of a high priest, a future messianic figure, mediation, intercession, sacrifice, or any connection to Melchizedek, making it entirely unrelated to the theme of "Christ as High Priest."
