Mark 14:70

And he denied it again
That he was one of the disciples of Jesus:

and a little after;
about an hour after, ( Luke 22:59 ) ;

they that stood by, said again to Peter, surely thou art one of
them;
one confidently affirmed that he was with Jesus, and another challenged him with seeing him in the garden with him, ( Luke 22:59 ) ( John 18:26 ) , and in general they were of opinion, that he must be one of that sect, giving this as a reason,

for thou art a Galilean:
as they supposed Jesus to be; and knowing that in Galilee he had chiefly preached, and wrought his miracles, and had there a large number of followers:

and thy speech agreeth [thereto];
he used words and phrases peculiar to the Galileans, and pronounced as they did: (See Gill on Matthew 26:73). This clause is omitted in the Vulgate Latin, and is wanting in Beza's most ancient copy; but is in the other copies, and in all the eastern versions.
