I'm using the American Standard Version:Mark 1:15
"and saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe in the gospel."
This statement by Jesus is one of the reasons the apostles thought they were living in the last days of the world.
Mark 4: 39
"And he awoke, and rebuked the wind, and said unto the sea, Peace, be still. And the wind ceased, and there was a great calm."
This is the climax of the story of Jesus sleeping on the boat after preaching. It shows the extent of his powers—and also the need to trust.
"And he called to him the multitude again, and said unto them, Hear me all of you, and understand"
This is just an introduction to what comes later: a series of teachings.
"And he taught, and said unto them, Is it not written, My house shall be called a house of prayer for all the nations? but ye have made it a den of robbers."
This is the commentary after Jesus has overturned the table of the money changers.
