David sent scouts and verified that Saul had indeed arrived. ¹ 

So they tracked them ¹  as far as the Jordan. The road was filled with clothes and equipment that the Syrians had discarded in their haste. ²  The scouts ³  went back and told the king.

When the scouts survey ¹  the land and see a human bone, they will place a sign by it, until those assigned to burial duty have buried it ²  in the valley of Hamon-Gog.
