Judges‬ ‭7:1-4, 8

“Early in the morning Jerub-Baal (Gideon) and all his men set up their camp at the spring of Harod. The Midianites were camped in the valley at the bottom of the hill called Moreh, north of Gideon and his men. Then the Lord said to Gideon, “I am going to help your men defeat the Midianites, but you have too many men. I don’t want the Israelites to forget me and brag that they saved themselves. So make an announcement to your men. Tell them, ‘Anyone who is afraid may leave Mount Gilead and go back home.’” At that time 22,000 men left Gideon and went back home, but 10,000 still remained. Then the Lord said to Gideon, “There are still too many men. Take the men down to the water, and I will test them for you there. If I say, ‘This man will go with you,’ he will go. But if I say, ‘That one will not go with you,’ then he will not go.”

So Gideon sent the other men of Israel home. He kept the 300 men with him. Those 300 men kept the supplies and the trumpets of the other men who went home. The Midianites were camped in the valley below Gideon’s camp.”
