'First' in the Bible

And my God put into my heart to gather together the nobles, and the rulers, and the people, for registration by genealogy. And I found a genealogical register of those that had come up at the first, and I found written in it:

And Ezra the priest brought the law before the congregation, both of men and women, and all that could hear with understanding, on the first day of the seventh month.

Also day by day, from the first day to the last day, he read in the book of the law of God. And they observed the feast seven days; and on the eighth day was a solemn assembly, according to the ordinance.
