John 21:1

After these things
The resurrection of Christ from the dead, his appearance to Mary Magdalene, and twice to his disciples; once when Thomas was absent, and at another time when he was present:

Jesus showed himself again to the disciples,
a third time, as in ( John 21:14 ) though not to them all; seven are only mentioned, as together, when he appeared to them:

at the sea of Tiberias;
the same with the sea of Galilee; see ( John 6:1 ) for after the second appearance of Christ to his disciples, they went from Jerusalem to Galilee, by the order of Christ, who appointed to meet them there, ( Matthew 28:10 Matthew 28:16 )

and on this way showed he himself;
the manner in which he made his appearance, and the persons to whom, are as follow.
