John Gill Commentary Luke 22:14

"And when the hour was come, he sat down, and the apostles with him." — Luke 22:14 (ASV)

And when the hour was come
When it was evening, the last of the two evenings, when it was dark, at least after six o'clock; (See Gill on Matthew 26:20). he sat down ;
or lay along on a couch, as was the custom; see the note, as before: and the twelve apostles with him ;
for Judas, after he had made his bargain with the chief priests, Scribes, and elders, came and took his place with the rest of the apostles, both to cover his sin, and to watch the best opportunity of betraying his master.
