Judges 20:16

14The children of Benjamin gathered themselves together out of the cities to Gibeah, to go out to battle against the children of Israel.

15The children of Benjamin were counted on that day out of the cities twenty-six thousand men who drew the sword, in addition to the inhabitants of Gibeah, who were counted seven hundred chosen men.

16Among all these soldiers there were seven hundred chosen men who were left-handed. Every one of them could sling a stone at a hair and not miss.

17The men of Israel, besides Benjamin, were counted four hundred thousand men who drew sword. All these were men of war.

18The children of Israel arose, went up to Bethel, and asked counsel of God. They asked, “Who shall go up for us first to battle against the children of Benjamin?” The LORD said, “Judah first.”
