'First' in the Bible

After the death of Joshua the people of Israel inquired of the LORD, "Who shall go up first for us against the Canaanites, to fight against them?"

And they named the city Dan, after the name of Dan their ancestor, who was born to Israel; but the name of the city was La'ish at the first.

The people of Israel arose and went up to Bethel, and inquired of God, "Which of us shall go up first to battle against the Benjaminites?" And the LORD said, "Judah shall go up first."

But the people, the men of Israel, took courage, and again formed the battle line in the same place where they had formed it on the first day.

And the Benjaminites said, "They are routed before us, as at the first." But the men of Israel said, "Let us flee, and draw them away from the city to the highways."

the men of Israel should turn in battle. Now Benjamin had begun to smite and kill about thirty men of Israel; they said, "Surely they are smitten down before us, as in the first battle."
