“Our fathers worshipped in this mountain; and ye say, that in Jerusalem is the place where men ought to worship.”
King James Version (KJV)
4:20 The instant she perceived this, she proposes what she thought the most important of all questions. This mountain - Pointing to Mount Gerizim. Sanballat, by the permission of Alexander the Great, had built a temple upon Mount Gerizim, for Manasseh, who for marrying Sanballat's daughter had been expelled from the priesthood and from Jerusalem, #Neh 13:28|. This was the place where the Samaritans used to worship in opposition to Jerusalem. And it was so near Sychar, that a man's voice might be heard from the one to the other. Our fathers worshipped - This plainly refers to Abraham and Jacob (from whom the Samaritans pretended to deduce their genealogy) who erected altars in this place: #Gen 12:6|,7, and #Gen 33:18|,20. And possibly to the whole congregation, who were directed when they came into the land of Canaan to put the blessing upon Mount Gerizim, #Deut 11:29|. Ye Jews say, In Jerusalem is the place - Namely, the temple.
Joh 4:20 Our fathers worshipped in this mountain, etc. Partly to turn attention from her sinful life, and partly to have him settle a great controversy, she appeals to him to say where men ought to worship God. The Jews went up to Jerusalem to the temple. The Samaritans built their temples on "this mountain", Mt. Gerizim. Note that the woman worshiped there because "our fathers" did. The "fathers" were wrong. Many now keep up infant sprinkling and other corruptions because their "fathers" practiced them.
