In that day shall there be upon the bells of the horses, HOLINESS UNTO THE LORD; and the pots in the LORD'S house shall be like the bowls before the altar. Upon the bells of the horses - They appear, formerly, to have had bells on horses, camels, etc., as we have now, to amuse the animals, and encourage them in their work. In some very fine Asiatic paintings now before me, I see bells both on horses, mules, and camels; little bells tied to their legs, and larger ones about their necks, particularly in the representation of a caravan passing through the valley of serpents, in the island of Serendib, now Ceylon. The margin reads bridles.
Holiness Unto The Lord - As the Gospel is a holy system, preaching holiness and producing holiness in those who believe, so all without, as well as within, shall bear this impress; and even a man's labor shall be begun and continued, and ended in the Lord; yea, and the animals he uses, and the instruments he works with, shall be all consecrated to God through Christ.
The pots - "The meanest utensil in the house of God, Nehemiah 10:29, shall be as the vessels of silver, and gold used in solemn sacrifice; they shall be like the bowls before the altar." - See Newcome.
