'Day by day' in the Bible

And day by day, from the first day till the last, he was reading from the book of the law of God. And they kept the feast for seven days: and on the eighth day there was a holy meeting, as it is ordered in the law.

For there was an order from the king about them and a regular amount for the music-makers, for their needs day by day.

And all Israel in the days of Zerubbabel and in the days of Nehemiah gave what was needed by the music-makers and the door-keepers day by day: and they made the offerings holy for the Levites; and the Levites did the same for the sons of Aaron.
