'First' in the Bible

My God put into my heart to gather together the nobles, and the rulers, and the people, that they might be reckoned by genealogy. I found the book of the genealogy of those who came up at the first, and I found written therein:

Ezra the priest brought the law before the assembly, both men and women, and all who 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. They kept the feast seven days; and on the eighth day was a solemn assembly, according to the ordinance.
