| Barnes' Notes on the Bible Sockets - More literally, bases, or foundations. Each base weighed a talent, that is, about 94 lbs. (see Exodus 38:27), and must have been a massive block. The bases formed a continuous foundation for the walls of boards, presenting a succession of sockets or mortices (each base having a single socket), into which the tenons were to fit. They served not only for ornament but also for the protection of the lower ends of the boards from the decay which would have resulted from contact with the ground.
Gill's Exposition of the Entire BibleAnd thou shall make forty sockets of silver under the twenty boards,.... Or bases (s), and which were properly the foundation of the tabernacle, on which it was settled and established; these sockets were the mortises for the two tenons of each board or plank to be placed in, and were as broad as the plank, and, joining each other, made one entire basis for the whole structure; each socket contained a talent of silver, and was made of the silver given at the numbering of the people, Exodus 38:25, and a talent of silver, according to Bishop Cumberland, amounted to three hundred and fifty three pounds, eleven shillings and some odd pence of our money: by which may be judged the whole value of this silver foundation, which, with the four sockets of the vail, consisted of one hundred of them, which answer to the one hundred talents of silver collected at the above offering: two sockets under one board for his two tenons, and two sockets under another board for his two tenons; and so in all the twenty boards, which took up the whole forty on the south side. (s) "bases", V. L. Pagninus, Montanus, Tigurine version, Piscator, Drusius.
Geneva Study BibleAnd thou shalt make forty sockets of silver under the twenty boards; two sockets under one board for his two tenons, and two sockets under another board for his two tenons.

Scofield Reference Notes[2] sockets of silver Silver symbolizes redemption. See Scofield Note: "Ex 25:1". See Scofield Note: "Ex 38:27". All the tabernacle rests upon silver except the hangings of the gate, the way of access. See Scofield Note: "Ex 27:17".
Matthew Henry's Concise Commentary26:15-30 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.
Matthew Henry's Whole Bible CommentaryVerses 15-30 Very particular directions are here given about the boards of the tabernacle, which were to bear up the curtains, as the stakes of a tent which had need to be strong, Isa. 54:2. These boards had tenons which fell into the mortises that were made for them in silver bases. God took care to have every thing strong, as well as fine, in his tabernacle. Curtains without boards would have been shaken by every wind; but it is a good thing to have the heart established with grace, which is as the boards to support the curtains of profession, which otherwise will not hold out long. The boards were coupled together with gold rings at top and bottom (v. 24), and kept firm with bars that ran through golden staples in every board (v. 26), and the boards and bars were all richly gilded, v. 29. Thus every thing in the tabernacle was very splendid, agreeable to that infant state of the church, when such things were proper enough to please children, to possess the minds of the worshippers with a reverence of the divine glory, and to affect them with the greatness of that prince who said, Here will I dwell; in allusion to this the new Jerusalem is said to be of pure gold, Rev. 21:18. But the builders of the gospel church said, Silver and gold have we none; and yet the glory of their building far exceeded that of the tabernacle, 2 Co. 3:10, 11. How much better is wisdom than gold! No orders are given here about the floor of the tabernacle; probably that also was boarded; for we cannot think that within all these fine curtains they trod upon the cold or wet ground; if it was so left, it may remind us of ch. 20:24, An altar of earth shalt thou make unto me. |
