Matthew Henry on Exodus 26:15-30
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 length being thirty cubits, twenty boards, one cubit and a half broad each, make about seventeen yards and a half, and the Breadth was about five yards.
John Gill on Exodus 26:28
And the middle bar in the midst of the boards shall reach from end to end. From east to west, as Jarchi interprets it; but this can only be said of the middle bar on the north and south sides of the tabernacle, for the middle bar at the west end was north to south: about this bar there is some difficulty, as that it is said to be "from end to end", as if that only was; whereas it is reasonable to suppose that the rest were so likewise; it may be, they might come somewhat short of reaching the end, whereas this did entirely; or rather the truer reason is, because the rest of the bars consisted of various parts; whereas this was a long bar of one entire piece, reaching from one end of the tabe…
