Charles Ellicott Commentary 2 Samuel 13:6

"So Amnon lay down, and feigned himself sick: and when the king was come to see him, Amnon said unto the king, Let her sister Tamar come, I pray thee, and make me a couple of cakes in my sight, that I may eat from her hand." — 2 Samuel 13:6 (ASV)

That I may eat at her hand. —This request from a sick person seemed natural and was readily granted.

Sent home. —Literally, into the house; that is, to the private apartments of the women—the harem.
