@ SBF - I'll stick to the Biblical evidence that the name of Jesus Christ was to be the priority in Christians' minds & speech, not "Jehovah."
After the millennium is over, that will obviously change. (1 Corinthians 15:28: "...that God may be all things to everyone.")
THE NAME FOR WITNESSING
Isaiah 62:2 - "... be called by a new name, which the very mouth of Jehovah will designate."
Acts 11:26 - "the disciples were by divine providence called Christians."

Acts 23:11 - "..... a thorough witness on the things about me in Jerusalem..."
Acts 26:16 -"I ...choose you as an attendant and a witness..respecting me"
Romans 8:16 - "The spirit itself bears witness with our spirit..."
1 Corinthians 1:6 - "even as the witness about the Christ..........."
1 Timothy. 2:6 - "......what is to be witnessed to at its own particular times."
2 Timothy 1:8 - "............of the witness about our Lord.. [Christ]"
1 John 5:9 - "the witness God gives...the fact that he has borne witness concerning his Son."
Revelation 1:9 - "....for speaking about God and bearing witness to Jesus."
Revelation 12:17 - ".......and have the work of bearing witness to Jesus."
Revelation 17:6 - "........and with the blood of the witnesses of Jesus."
Revelation 19:10 - ".....the work of witnessing to Jesus.... bearing witness to Jesus."
Revelation 20:4 - "............ for the witness they bore to Jesus."
THE NAME TO BE USED & CALLED UPON
1 Corinthians 1:2 - "....with all who....are calling upon the name of our Lord, Jesus Christ...."
1 Peter 4:14,16 - "If YOU are being reproached for the name of Christ, YOU are happy.... But if anyone sufers as a Christian, let him not feel shame......but let him keep on glorifying God in this [Jesus'] name."
John 3:18 - "....he has not exercised faith in the name of the only-begotten Son of God"

Acts 3:6 - "In the name of Jesus Christ the Nazarene, walk!"

Acts 16:18 - "“I order you in the name of Jesus Christ to come out of her.”
