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.

John Gill on Exodus 26:23
And two boards shalt thou make for the corners of the tabernacle in the two sides. For the northwest and southwest corners, in the north and south sides; concerning which Dr. Lightfoot thus writes (t): and the west end had six planks entire, besides a plank at either corner, joining end and sides together; these corner planks were of the same breadth that all the others were, and, thus set, the middle of the breadth of the one plank was laid close to the end of the south side, or to that plank that was furthest west; so that a quarter of a yard of the breadth of the corner plank was inward, to make up the tabernacle breadth, a quarter was taken up with the thickness of the side plank to whic…
