'Doing' in the Bible

It was right for us to have such a high priest, one who is holy and without evil, doing no wrong, having no part with sinners, and made higher than the heavens:

And every priest takes his place at the altar day by day, doing what is necessary, and making again and again the same offerings which are never able to take away sins.

But go on doing good and giving to others, because God is well-pleased with such offerings.
