Genesis 37:29

And Reuben returned unto the pit,.... It is very probable he had pretended to go somewhere on business, with an intention to take a circuit, and come to the pit and deliver his brother, and go home with him to his father. The Jews say b he departed from his brethren, and sat down on a certain mountain, that he might descend in the night and take Joseph out of the pit, and accordingly he came down in the night, and found him not. So Josephus c says, it was in the night when Reuben came to the pit, who calling to Joseph, and he not answering, suspected he was killed:

and, behold, Joseph [was] not in the pit; for neither by looking down into it could he see him, nor by calling be answered by him, which made it a clear case to him he was not there:

and he rent his clothes; as a token of distress and anguish of mind, of sorrow and mourning, as was usual in such cases; Jacob afterwards did the same, Genesis 37:34.
