John Gill Commentary 2 Samuel 13:11

"And when she had brought them near unto him to eat, he took hold of her, and said unto her, Come, lie with me, my sister." — 2 Samuel 13:11 (ASV)

And when she had brought [them] unto him to eat
Not only into the chamber, but to the side of the bed or couch where he had laid himself, or sat, in a proper position to answer his purpose:

he took hold of her ;
by the arm, or threw his hands about her:

and said unto her, come, lie with me, my sister ;
one would think the relation he observes she stood in to him would have checked him from making so vile a motion.
