Albert Barnes Commentary Luke 24:30

"And it came to pass, when he had sat down with them to meat, he took the bread and blessed; and breaking [it] he gave to them." — Luke 24:30 (ASV)

Sat at meat. Reclined at the table, or while he was at supper.

He took bread and blessed it, etc. This was the office of the master of a feast, and perhaps this first particularly attracted their attention. Though he was in their house, yet he acted as master of the feast, as he used to do with them before his death. Perhaps, also, as he gave them the bread, they observed the prints in his hands, and they knew that it was Jesus. This was not a sacramental, but a common supper; yet our Savior sought a blessing on the food, and thus set an example to all his followers to acknowledge God in their daily gifts, and to seek his benediction in all their enjoyments.
