Read 1 Samuel 6:9 Using Other Translations
And see, if it goeth up by the way of his own coast to Bethshemesh, then he hath done us this great evil: but if not, then we shall know that it is not his hand that smote us: it was a chance that happened to us.
and watch. If it goes up on the way to its own land, to Beth-shemesh, then it is he who has done us this great harm, but if not, then we shall know that it is not his hand that struck us; it happened to us by coincidence."
If they cross the border of our land and go to Beth-shemesh, we will know it was the LORD who brought this great disaster upon us. If they don’t, we will know it was not his hand that caused the plague. It came simply by chance.”
