John Gill's Exposition of the Whole Bible
1 Chronicles 28:2
Then David the king stood up upon his feet,.... Rose from the bed or couch on which he lay, as Kimchi thinks, being somewhat recovered of his paralytic disorder, and being willing to exert himself on this occasion; or he rose up from the seat or throne, on which he before sat, in honour to this august assembly before him, and that he might be the more easily heard; for which reason we are told r it was a custom with the ancients even for kings to stand up when they had a number of people about them they spoke to; and if anyone sat it was reckoned a new and strange thing; so Agamemnon, when wounded, did not speak sitting, until he had made an excuse for it:
and said, hear me, my brethren, and my people; having something of moment and importance to say unto them, and which required their diligent attention; and though they were his subjects, he calls them his brethren, being of the same nation and religion, and to show his modesty and humility; in which he was a type of Christ, the King of kings, see Hebrews 2:11
as for me, I had it in my heart to build an house of rest for the ark of the covenant of the Lord; where it might abide, and not be removed from place to place; the same he had told Solomon, 1 Chronicles 22:7
and for the footstool of our God; or "even for it", for the ark is meant, which is so called, Psalms 99:5 for as the Lord sat between the cherubim over the mercy seat, the lid of the ark, it was, speaking after the manner of men, a footstool to him:
and had made ready for the building; prepared materials for it; see 1 Chronicles 22:4.
