Judges 7:7-8

7:7 The Lord said to Gideon, “With the three hundred men who lapped I will deliver the whole army and I will hand Midian over to you. The rest of the men should go home.” 7:8 The men who were chosen took supplies and their trumpets. Gideon sent all the men of Israel back to their homes; he kept only three hundred men. Now the Midianites were camped down below in the valley.
