Albert Barnes Commentary Matthew 28:16

"But the eleven disciples went into Galilee, unto the mountain where Jesus had appointed them." — Matthew 28:16 (ASV)

Then the eleven disciples. Judas was dead, leaving only eleven of the original number of the apostles.

Into a mountain where Jesus had appointed them. This appointment is recorded in Matthew 26:32. On what particular mountain this was is not known. It is probable that Jesus, when he made the appointment, specified the place, which the evangelists have omitted.

Matthew has omitted many appearances which Jesus made to his disciples, which have been recorded by Luke, John, and Paul. See the harmony of the resurrection at the end of the chapter.
