'Myself' in the Bible

I thank God through Jesus Christ our Lord. So then I of myself with the mind, indeed, serve the law of God; but with the flesh the law of sin.

For I could wish that I myself were anathema from Christ for my brethren's sake, my kinsmen according to the flesh:

But what saith the answer of God unto him? I have left for myself seven thousand men, who have not bowed the knee to Baal.

And I myself also am persuaded of you, my brethren, that ye yourselves are full of goodness, filled with all knowledge, able also to admonish one another.
