'First' in the Bible

Then my God put it into my heart to assemble the nobles, the officials, and the people to be registered by genealogy. Then I found the register of the genealogy of those who came [from Babylon] first, and I found the following record:

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

Every day, from the first day to the last, Ezra read from the Book of the Law of God. They celebrated the feast for seven days; on the eighth day there was a [closing] solemn assembly in accordance with the ordinance.

and [we obligate ourselves] to bring the first fruits of our ground and the first fruits of all the fruit of every tree to the house of the Lord annually,

We will bring the first [and best] of our dough, our contributions, the fruit of every tree, the new wine and the [olive] oil to the priests, to the chambers of the house of our God, and the tithe of our ground to the Levites, for the Levites are the ones who receive the tithes in all the rural towns.
