'Name of the Lord' in the Bible

When David had finished offering the burnt offering and the peace offerings, he blessed the people in the name of the Lord.

So David went up at the word of Gad, which he spoke in the name of the Lord.

David said to Solomon, “My son, I had intended to build a house to the name of the Lord my God.

Now set your heart and your soul to seek the Lord your God; arise, therefore, and build the sanctuary of the Lord God, so that you may bring the ark of the covenant of the Lord and the holy vessels of God into the house that is to be built for the name of the Lord.”
