Theophylact of Ohrid
Catena Aurea · Lukasevangelium 13
The same day there came certain of the Pharisees, saying unto him, Get thee out, and depart hence: for Herod will kill thee. And he said unto them, Go ye, and tell that fox, Behold, I cast out devils, and I do cures to day and to morrow, and the third day I shall be perfected. Nevertheless I must walk to day, and to morrow, and the day following: for it cannot be that a prophet perish out of Jerusalem. O Jerusalem, Jerusalem, which killest the prophets, and stonest them that are sent unto thee; how often would I have gathered thy children together, as a hen doth gather her brood under her wings, and ye would not! Behold, your house is left unto you desolate: and verily I say unto you, Ye shall not see me, until the time come when ye shall say, Blessed is he that cometh in the name of the Lord.
But because they said unto Him, Depart from hence, for Herod seeks to kill thee, speaking in Galilee where Herod reigned, He shews that not in Galilee, but in Jerusalem it had been fore-ordained that He should suffer. Hence it follows, For it can not be that a prophet perish out of Jerusalem. When thou hearest, It can not be (or it is not fitting) that a prophet should perish out of Jerusalem, think not that any violent constraint was imposed upon the Jews, but He says this seasonably with reference to their eager desire after blood; just as if any one seeing a most savage robber, should say, the road on which this robber lurks can not be without bloodshed to travellers. So also no where else but in the abode of robbers must the Lord of the prophets perish. For accustomed to the blood of His prophets, they will also kill the Lord; as it follows, O Jerusalem, Jerusalem, which killest the prophets.
