1 Samuel 14:6-7

And Jonathan said to the young man that bare his armour, Come, and let us go over unto the garrison of these uncircumcised: it may be that the LORD will work for us: for there is no restraint to the LORD to save by many or by few. And his armourbearer said unto him, Do all that is in thine heart: turn thee; behold, I am with thee according to thy heart.
