'Day by day' in the Bible

And day by day, continuing stedfastly with one accord in the temple, and breaking bread at home, they took their food with gladness and singleness of heart,

praising God, and having favor with all the people. And the Lord added to them day by day those that were saved.

and the churches were strengthened in the faith and increased in numbers day by day.

So he kept up his discussions in the synagogue with the Jews and the pagans who were worshiping there, and also day by day in the public square with any who chanced to be there.

But, when some were hardening themselves, and refusing to be persuaded, speaking evil of the Way before the throng, withdrawing from them, he separated the disciples; day by day, reasoning in the school of Tyrannus.
