John Gill Commentary Mark 8:13

"And he left them, and again entering into [the boat] departed to the other side." — Mark 8:13 (ASV)

And he left them
As a perverse and hardened generation of men, and as such with whom it was not worth while to discourse:

and entering into the ship again ;
which brought him over, and waited for him:

departed to the other side ;
of the sea of Galilee, towards Bethsaida, (Mark 8:22) .
