Do we not say well? They show more and more how greatly they are stupified by Satan; for, though they are fully convicted, still they are enraged, and are not ashamed to show that they are utterly desperate. [1] Besides, though they bring a double reproach against Christ, still they wish to do nothing more than to say in a few words, that he is a detestable man, and that he is actuated by a wicked spirit. The Jews reckoned the Samaritans to be apostates and corrupters of the Law; and therefore, whenever they wished to stamp a man with infamy, they called him a Samaritan. Having no crime more heinous, therefore, to reproach Christ with, they seize at random, and without judgment, this vulgar taunt. To express it in a few words, we see that with effrontery they curse him, as men are wont to do when, infuriated like enraged dogs, they cannot find any thing to say.

Say we not well - Say we not truly.
Thou art a Samaritan - This was a term of contempt and reproach. See the notes at John 4:9. It had the force of charging him with being a heretic or a schismatic, because the Samaritans were regarded as such.
And hast a devil - See John 7:20. This charge they brought against him because he had said that they were not of God or were not the friends of God. This they regarded as the same as taking sides with the Samaritans, for the question between the Jews and Samaritans was, which of them worshipped God aright, John 4:20. As Jesus affirmed that the Jews were not of God, and as he, contrary to all their views, had gone and preached to the Samaritans John 4, they regarded it as a proof that he was disposed to take part with them. They also regarded it as evidence that he had a devil. The devil was an accuser or calumniator and as Jesus charged them with being opposed to God, they considered it as proof that he was influenced by such an evil spirit.
devil - In the original, demon. Not the prince or chief of the devils, but an evil spirit.

Thou art a Samaritan - This was the same, among them, as heretic, or schismatic, among us. This is the only time in which the Jews gave our Lord this title of reproach; and they probably grounded it on his having preached among them, and lodged in their villages. See the account in John 4:39, John 4:40; but Samaritan, among them, meant a person unworthy of any credit.
Hast a devil? - Art possessed by an evil spirit; and art, in consequence, deranged.

(15) Then answered the Jews, and said unto him, Say we not well that thou art a Samaritan, and hast a devil?
(15) The enemies of Christ act bravely for a while, but the Father will appear in his time to avenge the reproach that is done unto him in the person of his Son.

Then answered the Jews, and said unto him,.... Being incensed to the last degree, that he should say they were of their father the devil, and not of God; and that he spoke the truth, and no one could convince him of sin:
say we not well, that thou art a Samaritan? it seems they had said so before, though it is not recorded; and now they thought themselves justified in it, since he treated them, the true sons of Abraham, in such a manner; and the rather, since he had been lately among the Samaritans, and had in a parable spoken in favour of a Samaritan: they meant by this expression, that he was an irreligious man, and one that had no regard to the law of Moses; or at least played fast and loose with religion and the law, and was for any thing, as times served: the Jews had a very ill opinion of the Samaritans, on these accounts and to call a man a Samaritan, was all one as to call him an heretic, an idolater, or an excommunicated person; for such were the Samaritans with the Jews; they charged them with corrupting the Scriptures, and with worshipping idols, which were hid in Mount Gerizim; and they give us a dreadful account of their being anathematized by Ezra, Zorobabel, and Joshua; who, they say (r),
"gathered the whole congregation into the temple, and brought in three hundred priests, and three hundred children, and three hundred trumpets, and three hundred books of the law, in their hands; they blew the trumpets, and the Levites sung, and they anathematized the Samaritans, by the inexplicable name of God, and by the writing on tables, and with the anathema of the house of judgment, above and below; (saying,) let not any Israelite for ever eat of the fruit, or of the least morsel of a Samaritan; hence they say, whoso eateth the flesh of a Samaritan, it is all one as if he ate swine's flesh; also let not a Samaritan be made a proselyte, nor have a part in the resurrection of the dead; as it is said, "You have nothing to do with to build an house unto our God", Ezra 4:3, neither in this world, nor in the world to come: moreover, also let him have no part in Jerusalem; as it is said, "But you have no portion, nor, right, nor memorial in Jerusalem", Nehemiah 2:20; and they sent this anathema to the Israelites that were in Babylon, and they added thereunto, curse upon curse moreover, king Cyrus added an everlasting anathema to it, as it is said, "And the God that hath caused his name to dwell there, destroy", &c. Ezra 6:12.''
And hence, because the Samaritans were had in such abhorrence by the Jews, they would not ask a blessing over food in company with them (s), nor say Amen after they had asked one (t); nor indeed, after the better sort of them had asked, unless the whole blessing was distinctly heard (u), that so they might be sure there was no heresy in it; by all which it appears, how opprobrious this name was, and what a sad character was fixed upon a man that bore it; see Gill on John 4:9; and as Christ was called by the Jews a Samaritan, they having no name more hateful and reproachful to call him by, so the Christians are still in their writings called Cuthites, or Samaritans; and it is indeed with them a general name for all Gentiles and idolaters, or whom they esteem such:
and hast a devil; familiarity and converse with one; by which means they imagined he knew their thoughts, and their actions, and by his assistance performed his miracles; or they took him for a lunatic, or a madman; whose lunacy and madness proceeded from the devil, with whom he was possessed: and this rather seems to be the sense, since in John 8:52 the Jews say they knew he had a devil, which they concluded from his saying, that such that observed his words, and kept them, should never die; which they considered as the words of a man out of his senses, seeing all men, even the best of men die, they not understanding his meaning; whereas they could not gather from hence, that he dealt with familiar spirits; and what still confirms this sense is, that these two are joined together in John 10:20, "he hath a devil, and is mad", and such as were demoniacs, men possessed with devils, were either mad, or lunatic, and melancholy; see Matthew 8:28, compared with Mark 9:17. To which may be added, that it was a prevailing notion with the Jews, that madness and melancholy were owing to evil spirits, which had the predominancy over men: and seeing Christ was thought to be besides himself by his friends and relations, Mark 3:21, it need not be wondered at, that his enemies should fix such a character on him; nor was this an unusual one to be given to good men; the prophets and spiritual men of the Old Testament were accounted madmen, 2-Kings 9:11. And since our Lord was used in this abusive manner, it need not seem strange, that his followers should be treated in the same way; as the Apostle Paul and his companions in the ministry were, Acts 26:24; see John 10:20.

Observe Christ's disregard of the applause of men. those who are dead to the praises of men can bear their contempt. God will seek the honour of all who do not seek their own. In these verses we have the doctrine of the everlasting happiness of believers. We have the character of a believer; he is one that keeps the sayings of the Lord Jesus. And the privilege of a believer; he shall by no means see death for ever. Though now they cannot avoid seeing death, and tasting it also, yet they shall shortly be where it will be no more forever, Exodus 14:13.

Say we not well that thou art a Samaritan, and hast a devil?--What intense and virulent scorn! (See Hebrews 12:3). The "say we not well" refers to John 7:20. "A Samaritan" means more than "no Israelite at all"; it means one who pretended, but had no manner of claim to the title--retorting perhaps, this denial of their true descent from Abraham.

Thou art a Samaritan, and hast a devil? They resort to the language of passion and vituperation. Of all men they hated the Samaritans most, and hence this charge. They next accuse him, not of having a devil, but of being possessed with a demon, or evil spirit.

Say we not well - Have we not just cause to say, Thou art, a Samaritan - An enemy to our Church and nation; and hast a devil? - Art possessed by a proud and lying spirit?
