Exodus 25:30 -And you shall set the showbread (the bread of the Presence) on the table before Me always.
Leviticus 24: 5-9 – And you shall take fine flour and bake twelve cakes with it; two-tenths of an ephah shall be in each cake [of the showbread or bread of the Presence]. And you shall set them in two rows, six in a row, upon the table of pure gold before the Lord. You shall put pure frankincense [in a bowl or spoon] beside each row, that it may be with the bread as a memorial portion, an offering to be made by fire to the Lord.Every Sabbath day Aaron shall set the showbread in order before the Lord continually; it is on behalf of the Israelites, an everlasting covenant. And the bread shall be for Aaron and his sons, and they shall eat it in a sacred place, for it is for [Aaron] a most holy portion of the offerings to the Lord made by fire, a perpetual due [to the high priest].
The Shewbread that is obviously such an important part of The Table of Shewbread is also symbolic of God’s promise to us. The fine flour is uniform perfection, free of lumps and defects, just as Jesus was in his time on Earth. Sill, just as man cannot live on flour, we are not saved by the perfect life that Christ led. Redemption lies in his atoning death, which baking presents. With baked bread, we can gain life. Jesus by crucifying himself made himself the perfect bread of heaven.
The cake is translated from the Hebrew word Challah, which is a perforated cake, which represent Jesus on the cross, who was punctured five times on the Cross. In addition, the Bread was probably unleavened, which represents freedom from sin.
The Shewbread, or presence bread, is hallowed bread, only intended for the consumption of priests. In the New Testament however, true believers in Christ are made part of the priests of God. Therefore, born-again Christians have access, as sanctioned by His sacrifice, to have access to the True Bread from heaven.
