Albert Barnes Commentary Mark 16:14

"And afterward he was manifested unto the eleven themselves as they sat at meat; and he upbraided them with their unbelief and hardness of heart, because they believed not them that had seen him after he was risen." — Mark 16:14 (ASV)

See Barnes on Matthew 28:16 and Matthew 28:17-20.

As they sat at meat. The word meat here means food or meals. They were reclining at their meals.

And upbraided them, etc. This means He rebuked them or reproached them. This was done because, after all the evidence they had of His resurrection, they still did not believe.

This is a most important circumstance in the history of our Lord's resurrection. Never were men more difficult to be convinced of anything than they were of that fact.

And this shows conclusively that they had not conspired to impose on the world, that they had given up all for lost when He died, and that they did not expect His resurrection. All this is the strongest proof that He truly rose.

They were not convinced until it was impossible for them to deny it any longer.

Had they expected it, they would have readily grasped at the slightest evidence and even turned every circumstance in favor of such an event.

It may be added that it was impossible that eleven men of good natural understanding should have been deceived in so plain a case. They had been with Jesus three years; they perfectly knew His features, voice, and manner. And it was impossible that they should have been deceived by anyone who might have pretended to have been the Lord Jesus.
