And he said, “I am looking for my brothers. Please tell me where they are pasturing the flock.” Bible

“Please tell me.” Joseph assumed that the man was a local, and because a large flock being brought into the area would have caught the attention of the locals and been a subject of discussion, Joseph also assumed the man might know where they were. Amazingly, the man knew about them and even that they had gone on to Dothan, about 15 miles to the north.
