Barnes' Notes
My brethren - David retains the modest phrase of a king not born in the purple, but raised from the ranks of the people (see I Samuel 30:23; II Samuel 19:12). No later Jewish monarch would have thus addressed his subjects.
The footstool of our God - David views the ark as God' s "footstool," because he was enthroned above it visibly in the Shechinah, or luminous cloud, present from time to time above the mercy seat and between the cherubim (compare the marginal references).
