'Scouts' in the Bible

David sent scouts and verified that Saul had indeed arrived.

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

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