Exodus 25:30 - Joseph Benson’s Commentary on the Old and New Testaments

Thou shalt set upon the table the show bread Hebrew, Bread of the face or presence, because it was set before the ark, where God was peculiarly present. We call it show bread, because it was showed, or exhibited before God upon the sacred table, as a national weekly oblation, in the name of all the twelve tribes, for the loaves were twelve in number, and being an offering to God were to be eaten only by the priests in the holy place, Leviticus 24:5-9. Every loaf must have been of considerable size, since two-tenth deals, or two homers of flour were used for each, which are about six quarts English. This bread, set in two rows, six loaves in a row, 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 with the bread on their own tables. And it was 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.
