John Mark
Mark 16:14BSB·traditional attribution

Later, as they were eating, Jesus appeared to the Eleven and rebuked them for their unbelief and hardness of heart, because they did not believe those who had seen Him after He had risen.

Mark 16:14. Afterwards he appeared to the eleven, while they were sitting. The participle (ἀνακειμένοις) which some have rendered sitting at table, ought, in my opinion, to be simply rendered sitting; and it is not without reason that I take this view of it, if it be agreed that the Evangelist here describes the first appearance; for it would have been an unseasonable hour of supper about midnight.

Matthew Henry Presbyterian @wholebiblehenry

Here is, I. The conviction which Christ gave his apostles of the truth of his resurrection (Mar 16:14); He appeared to them himself, when they were all together, as they sat at meat, which gave him an opportunity to eat and drink with them, for their full satisfaction; see Act 10:41.

And he said unto them,.... Not at the same time, and place, as before; not on the first day of the week, on which he rose from the dead, but forty days after, just upon his ascension to heaven; see Mar 16:19; nor at Jerusalem, but in Galilee, where be appointed to meet his disciples, and did, when he gave them the following commission; see Mat 28:16.
