Having a look at the first paragraph and its sub-sections

4:1-9

Again he began to teach by the sea.
A very large crowd were assembled near him so that he went to sit in a ship in the sea. All the crowd were on the land and facing the sea. He (Jesus) taught them many things and presented his teaching in parables.
He said "Behold someone went out to sow seed.. And it happened as he sowed some of this fell by the way and the birds came and devoured it. Other seed fell on rocky places where there was not much earth. Immediately this sprang up because there was no depth of earth. And when the sun rose it was scorched. As it did not have enough roots it was withered. And other seed fell among thorns and the thorns came up and choked it and so it did not give fruit. And other seed again fell into the good earth. It came up and gave fruit up to thirty and sixty and even a hundred fold."
He said “Whoever has ears to hear this, let them hear.”
