John Lightfoot on Luke 4:27

[Naaman the Syrian.] These instances galled those of Nazareth upon a twofold account:

I. That they looked upon themselves as vilified by these examples; especially if we consider the occasion upon which our Saviour brought them. 'Thou hast wrought miracles in Capernaum; do something also here in thine own city.' 'No, you are unworthy of it, as Israel of old was unworthy of the prophets Elijah and Elisha, who were therefore sent amongst the Gentiles.'

II. That by these instances he plainly intimated the calling of the Gentiles, than which nothing could be more grating in the ear of the Jews. Elijah was sent to a heathen woman, and a heathen man was sent to Elisha: and both of them were turned from heathenism to the true religion. Those words therefore of Naaman, 2 Kings 5:17,18, I would thus render; "Thy servant will henceforth offer neither burnt offering nor sacrifice to strange gods, but unto Jehovah. And concerning this thing the Lord pardon thy servant [viz. concerning my former idolatry], that when my master went into the house of Rimmon to worship there, and leaned upon my hand, I also bowed myself in the house of Rimmon; for that I bowed myself in the house of Rimmon, the Lord pardon thy servant concerning this thing."
