1 Samuel 17:10

 

 

 

And the Philistine said, "I defy the armies of Israel this day; give me a man, that we may fight together."

 

Goliath was not defying the armies of Israel; he was defying God. And by doing so, he was ensuring his own demise. You seal your own ill fate when you try to come against God or what and whom He has ordained.
