Verse 13. - And a cubit. Rather, "And the cubit." The cubit by which the goats' hair tent-cloth, which was thirty cubits across (ver. 8), would exceed the linen covering, which was twenty-eight cubits (ver. 2), on either side of the tabernacle, was to be allowed to hang down, like a valance, hiding so far the golden boards of the tabernacle. The outer protection (ver. 14).

26:7-14 The curtains of meaner materials, being made both longer and broader, covered the others, and were defended by coverings of skins. The whole represents the person and doctrine of Christ, and the church of true Christians, and all heavenly things, which outwardly are mean, but inwardly, and in the sight of God, are glorious and precious.And a cubit on the one side, and a cubit on the other side o that which remaineth in the length of the curtains of the tent,.... The curtains of the tent, or the goat hair curtains, were two cubits longer than the other, and these are the two cubits, one on one side and the other on the other, which remained, and by which they were longer than the linen curtains:

it shall hang over the sides of the tabernacle; the north and south sides: on this side:

and on that side, to cover it; and as the above learned doctor observes (o), their length of fifteen yards reached half a yard lower on either side than the other curtains did, and yet they came not to the ground by a quarter of a yard; so that the silver foundations (of which afterwards) were always plain to be seen everywhere but at the west end.
