Origen (attributed)

(ubi sup.) Therefore, having entered into the boat He caused the sea to rise; And, lo, there arose a great tempest in the sea, so that the boat was covered by the waves. This tempest did not arise of itself, but in obedience to the power of Him Who gave commandment, who brings the winds out of his treasures. (Jer. 10:13.) There arose a great tempest, that a great work might be wrought; because by how much the more the waves rushed into the boat, so much the more were the disciples troubled, and sought to be delivered by the wonderful power of the Saviour.
