1. Exposition

What might be the significance of Jesus' teaching happening at the Sea of Galilee?

Mark 4:1 (ESV)

1 Again he began to teach beside the sea. And a very large crowd gathered about him, so that he got into a boat and sat in it on the sea, and the whole crowd was beside the sea on the land.

The location where this takes place is the Sea of Galilee. Jesus again begins to give instruction at the edge of the Sea. He had done this before (3:7); also then the instruction happened after certain events in Capernaum (3:1; 3:20). By his formulation, Mark reminds us emphatically of the earlier event. When Jesus acts like this now, it has the character of repetition.1
