'First' in the Bible

Now after the death of Joshua it came to pass, that the children of Israel asked the LORD, saying, Who shall go up for us against the Canaanites first, to fight against them?

And they called the name of the city Dan, after the name of Dan their father, who was born unto Israel: howbeit the name of the city was Laish at the first.

And the children of Israel arose, and went up to the house of God, and asked counsel of God, and said, Which of us shall go up first to the battle against the children of Benjamin? And the LORD said, Judah shall go up first.

And the people the men of Israel encouraged themselves, and set their battle again in array in the place where they put themselves in array the first day.

And the children of Benjamin said, They are smitten down before us, as at the first. But the children of Israel said, Let us flee, and draw them from the city unto the highways.

And when the men of Israel retired in the battle, Benjamin began to smite and kill of the men of Israel about thirty persons: for they said, Surely they are smitten down before us, as in the first battle.
