The shewbread was placed on the golden table of the sanctuary every Sabbath. They were twelve loaves in number, meaning one for every tribe, to be presented before the Lord. (See Leviticus 24:5-7 with Exodus 25:30). Those twelve loaves were carried in by the priests hot before the Lord, and the twelve which had been there from the Sabbath before were then taken away. Generally there was upon those occasions all offering of frankincense and salt. The Hebrews called them Lechem Panahim, the bread of faces: probably from being thus presented before the face of the Lord.
Surely the believer may discern strong pointings to Christ in this service. And the call of the church as strongly referred to him, when the united prayer of the congregation went up, "Behold, O God, our shield, and look upon the face of thine anointed." (Psalms 84:9)
