4. THE WALLS OF THE TABERNACLE.

(15-30) The various coverings which have been described had it for their object to roof over and protect an oblong chamber or "dwelling," within which God was to manifest Himself and to be worshipped. The directions which follow (Exodus 26:15-33) are for the construction of this chamber. It was to be enclosed by boards of shittim wood, fifteen feet high by two feet three inches wide, which were to be plated with gold, and made to stand upright by being inserted into solid sockets of silver. The two sides were to contain, each of them, twenty such boards, and thus to be forty-five feet long, while the connecting wall was to be composed of six such boards, together with two corner posts (Exodus 26:23), giving it a length, probably, of ten cubits, or fifteen feet.

(15) Boards . . . of shittim wood.--On the possibility of boards fifteen feet long by two feet three inches wide being cut from the Acacia seyal, see the last Note on Exodus 25:5.

Verse 15. - Boards... of shittim wood. These boards were to be fifteen feet long by two feet three inches broad, and, if they were each of a single plank, can scarcely have been furnished by any of the acacias which now grow in the Sinaitic peninsula. It is possible, however, that they were made up of two or more planks, since the name by which they are designated, kereth, is thought to be applied in Ezekiel 27:6, to the "deck of a ship." Standing up. The way in which they were to be made to "stand up" is explained in vers. 17 and 19. They were not to have one end sunk in the ground, but to be fitted by means of "tenons" into silver "sockets."

26:15-30 The sockets of silver each weighed about 115 pounds; they were placed in rows on the ground. In every pair of these sockets, a strong board of shittim-wood, covered with plates of gold, was fitted by mortises and tenons. Thus walls were formed for the two sides, and for the west end. The wall was further held together by bars, which passed through rings of gold. Over this the curtains were spread. Though movable, it was strong and firm. The materials were very costly. In all this it was a type of the church of God, built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief Corner-stone, Eph 2:20,21.And thou shalt make the boards for the tabernacle,.... Which were the pillars and supports, and properly the walls of it, which gave it its firmness and security, or otherwise the curtains would have been blown about by every wind: they were to be made

of shittim wood standing up; just as they grew, as a Jewish writer observes (p); these planks or boards were not to be laid along the lengthways of them, but to be set upright; and may denote such who are pillars in the house of God, and are to be upright both in heart and conversation, both ministers and private members; and indeed the church itself is the pillar and ground of truth, Galatians 2:9.
