'Yourself' in the Bible

But Paul said in a loud voice, Do yourself no damage, for we are all here.

Go with these, and make yourself clean with them, and make the necessary payments for them, so that they may be free from their oath: and everyone will see that the statements made about you are not true, but that you put yourself under rule, and keep the law.

And from whom you will be able, by questioning him yourself, to get knowledge of all the things which we say against him.
