A CALL TO WORSHIP

My alarm sounds like church bells ringing. This morning after turning it off I continued to hear bells ringing and it is not the first time. I decided to find out what the "Ringing of Bells" signifies.
Zecheriah Chapter 14 verse 20 talks about the DAY OF THE LORD
20 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.
In ExodusChapter 28 the bible talks about how Aaron went in before the Lord to minister and how the bells on the hem of the robe ringing was how people knew he wasn't dead. This was talked about in church but I now see the seriousness and urgency of what God is saying. He is saying the Day of the Lord is Near;Come in to the arc him who will; But Beware you must be holy to enter into the presence of a holy God.
Exodus 28
33.And beneath upon the hem of it thou shalt make pomegranates of blue, and of purple, and of scarlet, round about the hem thereof; and bells of gold between them round about:
34.A golden bell and a pomegranate, a golden bell and a pomegranate, upon the hem of the robe round about.
35.And it shall be upon Aaron to minister: and his sound shall be heard when he goeth in unto the holy place before the LORD, and when he cometh out, that he die not.
36.And thou shalt make a plate of pure gold, and grave upon it, like the engravings of a signet, HOLINESS TO THE LORD.
