And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. ESV
And he commanded them to be baptized in the name of Jesus Christ. Then they asked him to remain for some days. ESVIn Acts 19:5, onoma tou kyriou Iesou or name of the Lord Jesus.
On hearing this, they were baptized in the name of the Lord Jesus. ESV
And now why do you wait? Rise and be baptized and wash away your sins, calling on his name.’ ESV
And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God. ESVIn Acts 22:16 the personal pronoun "his" refers to Jesus. Saul, later Paul, was on his way to Damascus had been blinded and heard the voice of the Lord (22:6 ff.). Luke records the story of Ananias, a devout man, who prayed for Saul and he received his sight (22:13). Ananias then tells Saul that he was to see the "Righteous One" and to "hear" His voice (22:14). In fact, according to Ananias Saul would "be his witness" (22:15). Whose witness? The Righteous One. The one who in Acts 1:8 told his disciples that they "will be my witnesses...to the ends of the earth." (NRSV) The one for whom Saul would also be a witness was Jesus. Our same Lord who spoke to him on the road to Damascus.
