Upon the bells of the horses. The prophet, describing the holiness of the theocracy, uses imagery drawn from the ritual customs of the Law. "The bells," says Henderson, "were small metallic plates, suspended from the necks or heads of horses and camels, for the sake of ornament, and making a tinkling noise by striking against each other like cymbals."
Probably these plates had the names of the owners engraven on them. The Septuagint gives "bridle," which possibly the unusual word metzilloth may mean. HOLINESS (holy) UNTO THE LORD; Sanctum Domino (Vulgate); ἅγιον τῷ κυρίῳ παντοκράτορι.
This was the inscription upon the golden plate on the mitre of the high priest (Exodus 28:36). The affixing of this inscription on the trappings of horses signifies that the commonest things shall become holy, all things that men use for work, profit, or ornament shall be consecrated to God's service.
The pots in the Lord's house. The "pots" are vessels of inferior sanctity used for boiling the meat of the sacrifice (1 Samuel 2:14; 2 Chronicles 35:13). The bowls before the altar. These held the blood of the victims for sprinkling on the altar, and the sacred libations, and were considered of superior sanctity.
The prophet announces that now all shall be holy, the lower equal to the highest.
