Exodus 28:35

His sound shall be heard - The bells were doubtless intended to keep up the people's attention to the very solemn and important office which the priest was then performing, that they might all have their hearts engaged in the work; and at the same time to keep Aaron himself in remembrance that he ministered before Jehovah, and should not come into his presence without due reverence.

That he die not - This seems an allusion to certain ceremonies which still prevail in the eastern countries. Jehovah appeared among his people in the tabernacle as an emperor in his tent among his troops. At the doors of the tents or palaces of grandees was generally placed some sonorous body, either of metal or wood, which was struck to advertise those within that a person prayed for admittance to the presence of the king, etc. As the tabernacle had no door, but a veil, and consequently nothing to prevent any person from going in, Aaron was commanded to put the bells on his robe, that his sound might be heard when he went into the holy place before the Lord.

His sound - Its sound, i. e. the sound of the robe, that the people, who stood without, when they heard the sound of the bells within the tabernacle, might have a sensible proof that the high priest was performing the sacred rite in their behalf, though he was out of their sight.

That he die not - The bells also bore witness that the high priest was, at the time of his ministration, duly attired in the dress of his office, and so was not incurring the sentence of death (see also Exodus 28:43). An infraction of the laws for the service of the sanctuary was not merely an act of disobedience; it was a direct insult to the presence of Yahweh from His ordained minister, and justly incurred a sentence of capital punishment. Compare Exodus 30:21; Leviticus 8:35; Leviticus 10:7.
