John Mark
Mark 4:38KJV·traditional attribution
And he was in the hinder part of the ship, asleep on a pillow: and they awake him, and say unto him, Master, carest thou not that we perish?
Matthew Henry Presbyterian
This miracle which Christ wrought for the relief of his disciples, in stilling the storm, we had before (Mat 8:23, etc.); but it is here more fully related. Observe, 1. It was the same day that he had preached out of a ship, when the even was come, Mar 4:35.
Commenting on Mark 4:35-41

On a pillow - Προσκεφαλαιον probably means a little bed, or hammock, such as are common in small vessels. I have seen several in small packets, or passage boats, not a great deal larger than a bolster.
