'Name' in the Bible

so that the name of our Lord Jesus will be glorified in you [by what you do], and you in Him, according to the [precious] grace of our God and the Lord Jesus Christ.

Now we command you, believers, in the name of our Lord Jesus Christ and by His authority, that you withdraw and keep away from every brother or sister who leads an undisciplined life and does not live in accordance with the tradition and teaching that you have received from us.
