Charles Ellicott Commentary Acts 10:41

"not to all the people, but unto witnesses that were chosen before of God, [even] to us, who ate and drank with him after he rose from the dead." — Acts 10:41 (ASV)

Unto witnesses chosen before.—Better, appointed. The precise word which St. Luke uses occurs nowhere else in the New Testament, but is connected with the word rendered “ordained” in Acts 14:23.

Who did eat and drink with him.—The three recorded instances of this are found in Luke 24:30; Luke 24:42; John 21:13. This was, of course, the crucial test which showed that the Form on which the disciples had looked was no phantom of the imagination.
