'Ourselves' in the Bible

Thus in Judah it was said,“The strength of the burden bearers is failing,Yet there is much rubbish;And we ourselves are unableTo rebuild the wall.”

and I said to them: "We ourselves have bought back our brothers the Jews who were sold to the nations as we were able. But now you yourselves have sold your brothers so they may be sold to us!" They were silent and could not find a word [to say].

And I kept on with the work of this wall, and we got no land for ourselves: and all my servants were helping with the work.

Also we made ordinances for us, to charge ourselves yearly with the third part of a shekel for the service of the house of our God;

and [we obligate ourselves] to bring the first fruits of our ground and the first fruits of all the fruit of every tree to the house of the Lord annually,
