John Wesley on Exodus 25:23

This table was to stand not in the holy of holies, (nothing was in that but the ark with its appurtenances) but in the outer part of the tabernacle, called the sanctuary or holy place. This table was to be always furnished with the shew - bread, or bread of faces, twelve loaves, one for each tribe, set in two rows, six in a row. As the ark signified God's being present with them, so the twelve loaves signified their being presented to God. This bread was designed to be, a thankful acknowledgment of God's goodness to them in giving them their daily bread, a token of their communion with God; this bread on God's table being made of the same corn as the bread on their own tables. And a type of the spiritual provision which is made in the church, by the gospel of Christ, for all that are made priests to our God.
