2 Samuel 17:17

Now Jonathan and Ahimaaz were staying at En-rogel, where a servant girl would come and pass along information to them. They in turn would go and inform King David, for they dared not be seen entering the city.

Now Jonathan and Ahimaaz stayed by En-rogel; for they might not be seen to come into the city: and a wench went and told them; and they went and told king David.
