Theophylact of Ohrid

Even the Tyrians and Sidonians received benefit, despite being foreigners. Meanwhile His own kinsmen persecuted Him. So there is no benefit in kinship if there is no good character! Here even strangers came to Christ from afar, while the Jews persecuted Him who had come to them. On the contrary, those who went out from their homes and from their fatherland, that is, from the carnal way of life, follow Him; and therefore their wounds are healed, that is, the sins that wound the conscience, and the unclean spirits are driven out.
