The showbread table was placed in the holy place on the north side Exodus 26:35. Directions for preparing the showbread are given in Leviticus 24:5-9. It consisted of twelve large cakes of unleavened bread, which were arranged on the table in two piles, with a golden cup of frankincense on each pile. It was renewed every Sabbath day. The stale loaves were given to the priests, and the frankincense appears to have been lighted on the altar for a memorial. The showbread, with all the characteristics and significance of a great national Meat offering, in which the twelve tribes were represented by the twelve cakes, was to stand before Yahweh "perpetually," in token that He was always graciously accepting the good works of His people, for whom atonement had been made by the victims offered on the altar in the court of the sanctuary. The showbread or bread which is set forth would be more fairly rendered "bread of the presence." See the notes at Leviticus 24:5-9.

Shew-bread - לחם פנים lechem panim literally, bread of faces; so called, either because they were placed before the presence or face of God in the sanctuary, or because they were made square, as the Jews will have it. It is probable that they were in the form of cubes or hexaedrons, each side presenting the same appearance; and hence the Jews might suppose they were called the bread or loaves of faces: but the Hebrew text seems to intimate that they were called the bread of faces, פנים panim, because, as the Lord says, they were set לפני lephanai, before my Face. These loaves or cakes were twelve, representing, as is generally supposed, the twelve tribes of Israel. They were in two rows of six each. On the top of each row there was a golden dish with frankincense, which was burned before the Lord, as a memorial, at the end of the week, when the old loaves were removed and replaced by new ones, the priests taking the former for their domestic use.
It is more difficult to ascertain the use of these, or what they represented, than almost any other emblem in the whole Jewish economy. Many have conjectured their meaning, and I feel no disposition to increase their number by any addition of my own. The note on Exodus 25:23, from Dr. Cudworth, appears to me more rational than any thing else I have met with. The tabernacle was God's house, and in it he had his table, his bread, his wine, candlestick, etc., to show them that he had taken up his dwelling among them. See Clarke's note on Exodus 25:23.

And thou shall set upon the table shewbread before me always. Which consisted of twelve cakes loaves, set in two rows upon the table, and stood there a whole week, and every sabbath were renewed; and when the old ones were took away, which were eaten by the priests, new ones were set, so that they were always before the Lord; and being continually before him, were called shewbread, or "bread of faces", being always before the face of God. This was a memorial of the goodness of God in daily providing bread for the people of Israel, and was presented to him as a thankful acknowledgment of it, and being the same they ate at their own tables; and this being eaten by the priests, was expressive of the communion between God and them, they being guests of his, and feeding on the same provisions. This shewbread may be considered either as typical of the church and people of God, who are all one bread, 1-Corinthians 10:17, these pure and unleavened cakes may denote their purity, simplicity, and sincerity, being without the leaven of malice and wickedness; the number twelve, the twelve tribes of Israel, the whole spiritual Israel of God; their being called shewbread, or bread of faces, the presentation of themselves to the Lord in public worship, and their being ever under the eye and care of God; their being set on the table, their standing in Christ, and security by him, who is the foundation of the apostles and prophets; and being set in rows, their order and harmony; being renewed every sabbath, the constancy of their worship, and the succession of them in all ages; the frankincense put on each row, the acceptance of their persons and services through the incense of Christ's mediation; the border round about them, the power of Christ around them to keep them from falling: or else as typical of Christ himself, of his being the food of believers, the bread of life: the shewbread of fine flour may fitly signify Christ, the finest of the wheat, the corn of heaven, the bread that comes from thence; its quantity, twelve cakes, the sufficiency of food with him, bread enough and to spare for the whole Israel of God; its continuance, the permanency of Christ as the food believers have always to feed upon; the frankincense on it, the gratefulness of Christ to such, to whom his flesh is meat indeed, and his blood drink indeed; and being set for priests, and only for them, may show that Christ is only food to such who are made priests to God: or this may be an emblem of the intercession of Christ, who is the Angel of God's presence, ever before him, and represents the whole Israel of God, for whom he intercedes; and his intercession is continual, he ever lives to make intercession for them, and that is always acceptable to God. The twelve loaves, Josephus (a) says, signify the year divided into so many months.

showbread--literally, presence bread, so called because it was constantly exhibited before the Lord, or because the bread of His presence, like the angel of His presence, pointed symbolically to Christ. It consisted of twelve unleavened loaves, said traditionally to have been laid in piles of six each. This bread was designed to be a symbol of the full and never-failing provision which is made in the Church for the spiritual sustenance and refreshment of God's people.

Bread of the face (פּנים לחם), the mode of preparing and placing which is described in Leviticus 24:5., was to lie continually before (לפני) Jehovah. These loaves were called "bread of the face" (shew-bread), because they were to lie before the face of Jehovah as a meat-offering presented by the children of Israel (Leviticus 24:8), not as food for Jehovah, but as a symbol of the spiritual food which Israel was to prepare (John 6:27, cf. John 4:32, John 4:34), a figurative representation of the calling it had received from God; so that bread and wine, which stood upon the table by the side of the loaves, as the fruit of the labour bestowed by Israel upon the soil of its inheritance, were a symbol of its spiritual labour in the kingdom of God, the spiritual vineyard of its Lord.
