The characteristic function, however, of the Jewish priesthood was their ministry in public worship, in which they represented the people before Jehovah. In this connection public worship does not necessarily imply that the public were present, or that the worship in question was the united act of a great assembly. Such worshipping assemblies were not uncommon, especially at the feasts; but ordinary public worship was worship on behalf of the people, not by the people. The priests and Levites were part of an elaborate system of symbolic ritual. Worshippers might gather in the Temple courts, but the Temple itself was not a place in which public meetings for worship were held, and the people were not admitted into it. The Temple was Jehovah’s house, and His presence there was symbolised by the Ark. In this system of ritual the priests and Levites represented Israel; their sacrifices and ministrations were the acceptable offerings of the nation to God. If the sacrifices were duly offered by the priests “according to all that was written in the law of Jehovah, and if the priests with trumpets and the Levites with psalteries, and harps, and cymbals duly ministered before the ark of Jehovah to celebrate, and thank, and praise Jehovah, the God of Israel,” then the Divine service of Israel was fully performed. The whole people could not be regularly present at a single sanctuary, nor would they be adequately represented by the inhabitants of Jerusalem and casual visitors from the rest of the country. Three times a year the nation was fully and naturally represented by those who came up to the feasts, but usually the priests and Levites stood in their place.
