Augustine of Hippo
Catena Aurea · Johannesevangelium 6
When Jesus therefore perceived that they would come and take him by force, to make him a king, he departed again into a mountain himself alone. And when even was now come, his disciples went down unto the sea, And entered into a ship, and went over the sea toward Capernaum. And it was now dark, and Jesus was not come to them. And the sea arose by reason of a great wind that blew. So when they had rowed about five and twenty or thirty furlongs, they see Jesus walking on the sea, and drawing nigh unto the ship: and they were afraid. But he saith unto them, It is I; be not afraid. Then they willingly received him into the ship: and immediately the ship was at the land whither they went.
(de Con. Ev. ii. c. xlvii) This is not at all inconsistent with what we read, that He went up into a mountain apart to pray: (Mat. 14:23) the object of escape being quite compatible with that of prayer. Indeed our Lord teaches us here, that whenever escape is necessary, there is great necessity for prayer.
