Albert Barnes Commentary Mark 4:36

"And leaving the multitude, they take him with them, even as he was, in the boat. And other boats were with him." — Mark 4:36 (ASV)

Even as he was in the ship. They took him without making any preparation for the voyage; without providing any food or clothing. He was sitting in a ship, or boat, instructing the people. In the same boat, probably ill-fitted to encounter a storm on the lake, they sailed. This would render their danger more imminent, and the miracle more striking.

There were also with him other little ships. Belonging probably to the people, who, seeing him sail, resolved to follow him.
