For which thou shalt cast forty sockets of silver, that under every board may be put two sockets at the two corners.

And thou shalt make forty bases of silver under the twenty boards; two bases under one board for its two tenons, and two bases under another board for its two tenons.

and forty sockets of silver thou dost make under the twenty boards, two sockets under the one board for its two handles, and two sockets under the other board for its two handles.

With forty silver bases under the twenty boards, two bases under every board to take its tongues.

For these, you shall cast forty bases of silver, so that two bases will lie under each panel at its two corners.

Et quadraginta bases argenteas facies sub viginti tabulis, duas bases sub una tabula, pro duobus cardinibus ejus: et duas bases sub tabula altera, pro duobus cardinibus ejus.

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.

And 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.
