Matthew Henry on 2 Samuel 13:1-20
We have here a particular account of the abominable wickedness of Amnon in ravishing his sister, a subject not fit to be enlarged upon nor indeed to be mentioned without blushing, that ever any man should be so vile, especially that a son of David should be so. Amnon's character, we have reason to think, was bad in other things; if he had not forsaken God, he would never have been given up to these vile affections. Godly parents have often been afflicted with wicked children; grace does not run in the blood, but corruption does.

The cakes seem to have been a kind of fancy bread, in the preparation of which Oriental ladies take great delight. Tamar, flattered by the invitation, lost no time in rendering the required service in the house of her sick brother.
Adam Clarke on 2 Samuel 13:3
Jonadab was a very subtle man - And most diabolic advice did he give to his cousin. We talk of the simplicity and excellence of primitive times!

John Gill on 2 Samuel 13:7
Then David sent home to Tamar,.... Who perhaps was not in the king's palace, but at her brother Absalom's house, 2 Samuel 13:20,
saying, go now to thy brother Amnon's house; who also had a separate house and equipage, being the king's son, and his eldest son:
and dress him meat; such as he may desire, and his stomach will bear.
