'First' in the Bible

Then my God put it into my mind to assemble the nobles, the officials, and the people to be registered by genealogy. I found the genealogical record of those who came back first, and I found the following written in it:

On the first day of the seventh month, Ezra the priest brought the law before the assembly of men, women, and all who could listen with understanding.

Ezra read out of the book of the law of God every day, from the first day to the last. The Israelites celebrated the festival for seven days, and on the eighth day there was an assembly, according to the ordinance.

We will bring a loaf from our first batch of dough to the priests at the storerooms of the house of our God. We will also bring the firstfruits of our grain offerings, of every fruit tree, and of the new wine and oil. A tenth of our land’s produce belongs to the Levites, for the Levites are to collect the one-tenth offering in all our agricultural towns.
