Albert Barnes Commentary Luke 24:17

"And he said unto them, What communications are these that ye have one with another, as ye walk? And they stood still, looking sad." — Luke 24:17 (ASV)

What manner of communications, etc. What is the subject of your conversation? What is it that has so much affected your minds? They were deeply affected in the recollection of the death of Jesus; and, as befitted all Christians, they were conversing about him, and were sad at the overwhelming events that had come upon them.
