Genesis 40:6

And Joseph came in unto them in the morning
For though Joseph and they were in the same prison, yet not in the same ward. Aben Ezra thinks that Joseph lodged in the dungeon in the night, ( Genesis 40:15 ) ; and was let out in the morning to wait on these prisoners; but the great interest he had in the keeper of the prison, and the favour shown him by the captain of the guard, in putting such prisoners under his care, will easily make one conclude, that Joseph now had a better lodging than that; though it had been his case, he was now provided with a better apartment in the prison; and when he arose in the morning, like a careful and faithful servant, he came to the ward where the prisoners under his care were, to see that they were safe, and what they wanted: and looked upon them, and, behold, they [were] sad;
they looked sorrowful, dejected, and uneasy.
