1 Samuel 14:8

6Jonathan said to the young man who bore his armor, “Come! Let’s go over to the garrison of these uncircumcised. It may be that the LORD will work for us, for there is no restraint on the LORD to save by many or by few.”

7His armor bearer said to him, “Do all that is in your heart. Go, and behold, I am with you according to your heart.”

8Then Jonathan said, “Behold, we will pass over to the men, and we will reveal ourselves to them.

9If they say this to us, ‘Wait until we come to you!’ then we will stand still in our place and will not go up to them.

10But if they say this, ‘Come up to us!’ then we will go up, for the LORD has delivered them into our hand. This shall be the sign to us.”
