Matthew 28:16

Then the eleven disciples went away into Galilee, into a mountain where Jesus had appointed them.

Then the eleven disciples went away into Galilee - but certainly not before the second week after the resurrection, and probably somewhat later.

Into a mountain [ to (G3588 ) oros (G3735 )], where Jesus had appointed them. It should have been rendered 'the mountain,' meaning some certain mountain which He had named to them-probably the night before He suffered, when He said, "After I am risen, I will go before you into Galilee" (Matthew 26:32; Mark 14:28). What it was can only be conjectured; but of the two between which opinions are divided-the Mount of the Beatitudes or Mount Tabor-the former is much the more probable, from its nearness to the sea of Tiberias, where last before this the Narrative tells us that He met and dined with seven of them. (John 21:1, etc.) That the interview here recorded was the same with that referred to in one place only - 1 Corinthians 15:6 - when "He was seen of above five hundred brethren at once; of whom the greater part remained unto that day, though some were fallen asleep," is now the opinion of the ablest students of the Evangelical History. Nothing can account for such a number as five hundred assembling at one spot but the expectation of some promised manifestation of their risen Lord; and the promise before His resurrection, twice repeated after it, best explains this immense gathering.
