'First' in the Bible

In the fortieth year, on the first day of the eleventh month, Moses spoke to the children of Israel, according to all that the Lord had commanded him to give to them,

I fell down before the Lord, as at the first, forty days and nights; I neither ate bread nor drank water, because of all your sin which you had committed in doing what was evil in the sight of the Lord to provoke Him to anger.

“I, moreover, stayed on the mountain forty days and forty nights like the first time, and the Lord listened to me that time also; the Lord was not willing to destroy you.

But you shall surely kill him; your hand shall be first against him to put him to death, and afterwards the hand of all the people.

For seven days no leaven shall be seen with you in all your territory, and none of the flesh which you sacrifice on the evening of the first day shall remain overnight until morning.

The hand of the witnesses shall be first against him to put him to death, and afterward the hand of all the people. So you shall purge the evil from your midst.

You shall give him the first fruits of your grain, your new wine, and your oil, and the first shearing of your sheep.

that you shall take some of the first of all the produce of the ground which you bring in from your land that the Lord your God gives you, and you shall put it in a basket and go to the place where the Lord your God chooses to establish His name.

Now behold, I have brought the first of the produce of the ground which You, O Lord have given me.’ And you shall set it down before the Lord your God, and worship before the Lord your God;

“Then he provided the first part for himself,For there the ruler’s portion was reserved;And he came with the leaders of the people;He executed the justice of the Lord,And His ordinances with Israel.”
