indeed, he will build Yahweh’s temple, and he will have the glory, and will sit and rule on his throne; and he will be a priest on his throne, and the counsel of peace will be between both offices.’” Bible

“both offices.” That is, the office of king and the office of High Priest. Jesus will be king, and he will be a High Priest after the order of Melchizedek (Heb. 7:11, 17).
