SEV Biblia, Chapter 28:35
Y estará sobre Aarón cuando ministrare; y se oirá su sonido cuando él entrare en el santuario delante del SEÑOR y cuando saliere; para que no muera.
Clarke's Bible Commentary - Exodus 28:35
Verse 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, &c. 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.
Matthew Henry Commentary
Verses 31-39 - The robe of the ephod was under the ephod, and reached down to the knees, without sleeves. Aaron must minister in the garments appointed We must serve the Lord with holy fear, as those who know they deserv to die. A golden plate was fixed on Aaron's forehead, engraven with "Holiness to the Lord." Aaron was hereby reminded that God is holy, an that his priests must be holy, devoted to the Lord. This must appear in their forehead, in open profession of their relation to God. It must be engraven like the engravings of a signet; deep and durable; not painted so as to be washed off, but firm and lasting; such must our holiness to the Lord be. Christ is our High Priest; through him sins are forgive to us, and not laid to our charge. Our persons, our doings, ar pleasing to God upon the account of Christ, and not otherwise.
