'Myself' in the Bible

But Peter took him up, saying, Stand up; I myself also am a man.

But none of these things move me, neither count I my life dear unto myself, so that I might finish my course with joy, and the ministry, which I have received of the Lord Jesus, to testify the gospel of the grace of God.

Then Paul, after that the governor had beckoned unto him to speak, answered, Forasmuch as I know that thou hast been of many years a judge unto this nation, I do the more cheerfully answer for myself:

And herein do I exercise myself, to have always a conscience void of offence toward God, and toward men.

Then Agrippa said unto Festus, I would also hear the man myself. To morrow, said he, thou shalt hear him.

I think myself happy, king Agrippa, because I shall answer for myself this day before thee touching all the things whereof I am accused of the Jews:

I verily thought with myself, that I ought to do many things contrary to the name of Jesus of Nazareth.
