1 Samuel 14:6-7

6Jonathan 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.”

7And his armor bearer said to him, “Do everything that is in your heart (mind); here I am with you in whatever you think [best].”
