'One by one' in the Bible

For none of them was in want, for as many of them as were owners of farms or houses proceeded to sell them, one by one, and continued to bring the money received for the things sold

Then they laid their hands upon them, and one by one they received the Holy Spirit.

So ever be on your guard and always remember that for three years, night and day, I never ceased warning you one by one, and that with tears.
