John Gill Commentary 2 Samuel 13:10

"And Amnon said unto Tamar, Bring the food into the chamber, that I may eat from thy hand. And Tamar took the cakes which she had made, and brought them into the chamber to Amnon her brother." — 2 Samuel 13:10 (ASV)

And Amnon said unto Tamar, bring the meat into the chamber ,
&c.] An inner chamber, at a greater distance, where they might be more secret, and out of the reach of the hearing of any of his domestics:

that I may eat of thine hand ;
this he pretended, though his design was of another kind:

and Tamar took the cakes which she had made, and brought [them] into
the chamber to Amnon her brother ;
being quite innocent herself, and having no suspicion of a brother having any ill design upon her, she made no scruple of going into an inner chamber alone with him.
