Charles H. Spurgeon on Psalms 78:54

He brought them to the border of his sanctuary, or holiness; that is, to the holy land; so called in diverse respects, but especially because of his sanctuary, the place of his residence; to which he makes all the land to be but as bounds and limits, because of the eminency of that place, the holiness whereof did, as it were, spread to all other parts of the land, as if the whole had been a sanctuary, and consecrated ground. It is therefore to the honour of the whole land, as well as of the sanctuary, that he calleth it, the holy border, a border of his sanctuary. Westminster Assembly's Annotations.
