Luke 8:22-25
Some ancient stories told of powerful individuals able to subdue even the forces of nature, but these were nearly always gods or, less commonly, heroes of the distant past. In Jewish tradition, the one who ruled the winds and sea was God himself (Ps 107:29), though a few pious men were reputed to be able to persuade him to send rain. The surprise of the disciples at Jesus’ power is thus easy to understand.
Storms often rose suddenly on the lake called the Sea of Galilee; these fishermen had usually stayed closer to Capernaum and are unprepared for a squall this far from shore. The only place one could sleep in a small fishing boat with water pouring in from a storm would be on the elevated stern, where one could use the wooden or leather-covered helmsman’s seat, or a pillow sometimes kept under that seat, as a cushion to rest one’s head.
