John Wesley on 2 Samuel 13:26

Let Amnon - For the king designed (as the following words shew) to keep him at home with him, as being his eldest son, and heir of his kingdom: otherwise Absalom would never have made particular mention of him; which now he was forced to do. Nor did this desire of Amnon's presence want specious pretences, as that seeing the king would not, he who was next to him might, honour him with his company; and that this might be a publick token of friendship between him and his brother, notwithstanding the former occasion of difference.
