John 4:25-26

The woman saith, I know that Messias cometh She probably meant from among the Jews. The Jews and Samaritans, though so much at variance in other things, agreed in the expectation of the Messiah and his kingdom. This the Samaritans probably grounded on the writings of Moses, which, as has been observed, they received as of divine authority. It was also, doubtless, strengthened by the slight acquaintance which they had with the writings of the prophets, and by the hopes which they knew were entertained by the Jewish nation, not to mention the general expectation which now prevailed in many parts of the East, that a great prince was soon to arise in Judea; which is called Christ It would appear from the manner in which this clause is expressed, that it was spoken by the woman; and yet it is manifest that could not have been the case. “Our Lord and the woman spoke a dialect of the Chaldee, at that time the language of the country, and in the New Testament called Hebrew, wherein Messiah was the proper term, and consequently needed not to be explained to either of them into Greek, which they were not speaking, and which was a foreign language to both. But it was very proper for the evangelist, who wrote in Greek, and in the midst of those who did not understand Chaldee, when introducing an oriental term, to explain it for the sake of his Greek readers.” Campbell. When he is come, he will tell us all things Relating to the service of God, which it is necessary for us to know: he will supply our defects of knowledge, rectify our mistakes, and put an end to all our disputes, and will make us fully acquainted with the mind and will of God. The woman seems to have spoken this with joy for what she had already learned, and with a desire of fuller instruction. Jesus saith Hasting to satisfy her desire before his disciples came; I that speak unto thee am he Our Lord did not speak of himself thus plainly to the Jews, because, as they were full of expectation that the Messiah, when he came, would erect a glorious temporal kingdom, and constitute them a free, happy, and prosperous people, if Jesus had openly professed to be that expected deliverer of their nation, many of them would doubtless have taken up arms in his favour, and others have accused him to the Roman governor. Yet he did, in effect, declare what implied it, though he declined using and applying to himself the particular title. For in a multitude of places he represented himself both as the Son of man, and as the Son of God: both which expressions were generally understood by the Jews as peculiarly applicable to the Messiah.
