'Natural' in the Bible

Keep watching it. If it goes up along the road to its own territory to Beth-shemesh, it's the LORD who has done this great evil to us. But if it does not, then we will know that he wasn't pressuring us. It happened to us as a natural event."

And David said, By the living Lord, the Lord will send destruction on him; the natural day of his death will come, or he will go into the fight and come to his end.
