Bede the Venerable
Catena Aurea · Lukasevangelium 6
And he came down with them, and stood in the plain, and the company of his disciples, and a great multitude of people out of all Judæa, and Jerusalem, and from the sea coast of Tyre and Sidon, which came to hear him, and to be healed of their diseases; And they that were vexed with unclean spirits: and they were healed. And the whole multitude sought to touch him: for there went virtue out of him, and healed them all.
By the sea coast he does not refer to the neighbouring sea of Galilee, because this would not be accounted wonderful, but it is so called from the great sea, and therein also Tyre and Sidon may be comprehended, of which it follows, Both of Tyre and Sidon. And these states being Gentile, are purposely named here, to indicate how great was the fame and power of the Saviour which had brought even the citizens of the coast to receive His healing and teaching. Hence it follows, Which came to hear him.
