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. Went up to the house of God - Some think that a deputation was sent from Shiloh, where Phinehas the high priest was, to inquire, not concerning the expediency of the war, nor of its success, but which of the tribes should begin the attack. Having so much right on their side, they had no doubt of the justice of their cause. Having such a superiority of numbers, they had no doubt of success. See the note on Judges 20:1.
And the Lord said, Judah - But he did not say that they should conquer.
