Mark 2:13

"Again" (Gr. palin) identifies this incident as a different occasion (cf. Mark 1:16). Jesus had been in Capernaum, which was very close to the Sea of Galilee, but now He returned to the water’s edge where He could teach the large crowds that followed Him (cf. Mark 1:45; Mark 2:13; Mark 3:7; Mark 3:13; Mark 4:1; Mark 5:21; et al.).

"This action becomes meaningful when it is seen as part of a recurring pattern in Mark’s Gospel. After a demonstration of the saving power of God, Jesus withdraws from the populace to a lonely region, whether the wilderness, the mountain or the sea. . . . Like the return to the wilderness, the move to the sea entails a deliberate entrance into the sphere of forces which manifest their hostility to God." [Note: Lane, p. 100.]
