1 Samuel 14:6-10

Jonathan said to his young armor bearer, “Come, let us cross over to the garrison of these uncircumcised men; it may be that the LORD will work for us. For there is nothing to prevent the LORD from saving, whether by many or by few.” And his armor bearer said to him, “Do everything that is in your heart (mind); here I am with you in whatever you think [best].” Jonathan said, “See now, we are going to cross over to the [Philistine] men and reveal ourselves to them. If they say to us, ‘Wait until we come to you,’ then we will stand in our place and not go up to them. But if they say, ‘Come up to us,’ we will go up, for the LORD has handed them over to us; and this shall be the sign to us.”
