'Required' in the Bible

For there was a commandment from the king concerning them, and a settled provision for the singers, as every day required.

And all Israel in the days of Zerubbabel, and in the days of Nehemiah, gave the portions of the singers and the porters, as every day required: and they set apart that which was for the Levites; and the Levites set apart that which was for the sons of Aaron.
