When we used the word "name," it is the way we address something or someone. However in Scripture proper names have significance. Sometimes the same person will have two names.
For example, when Rachel died her son was called, "Bennomi," "the son of my sorrow."
It came about as her soul was departing (for she died), that she named him Ben-oni; but his father called him Benjamin Gen 35:18
Jacob, the father, named him, "Benjamin," "son of my right hand."
God's Character Is Revealed
God's name, as revealed in the Bible, is more than a combination of sounds—it stands for His character. God reveals Himself by making known or proclaiming His name or character.

Scripture also says.
Then the LORD came down in the cloud and stood there with him and proclaimed his name, the LORD. And he passed in front of Moses, proclaiming, "The LORD, the LORD, the compassionate and gracious God, slow to anger, abounding in love and faithfulness (Exd 34:5-6).
We Are to Call upon His Name
