4:2 but his disciples. These disciples had formerly been John’s disciples, and in effect were continuing John’s ministry, now under Jesus with greater meaning.
4:5 Sychar. Sychar was near ancient Shechem, where Jacob had bought land from Hamor, Shechem’s father. Later, Joseph had been buried there (Genesis 33:19; Joshua 24:32). It was not far from the capital of the province of Samaria and also near Mount Gerizim, the worship center of the Samaritans (John 4:20). Samaria, Judaea and Galilee were all Roman provinces at this time, but Jerusalem and Samaria had formerly (before the exile) been the capitals of Judah and Israel, the southern and northern kingdoms, respectively.
4:6 Jacob’s well. There is no specific well mentioned in Genesis in connection with the times of Jacob. The well which is today exhibited to tourists as Jacob’s well, however, is probably the same as the one which the woman of Samaria called his well. This area, which is near Samaria, was originally bought by Jacob (Genesis 33:18-19).
4:7 woman of Samaria. Apparently in order to talk to this woman, Jesus deliberately took this route through Samaria to get to Galilee, even though, normally, “the Jews have no dealings with the Samaritans” (John 4:9). He knew her need and that of the other people of the region (John 4:18,39), and “must needs go through Samaria” (John 4:4). In so doing, He was “leaving us an example, that (we) should follow His steps” (I Peter 2:21), both of personal soul-winning and of rejecting ethnic prejudice.
4:14 shall never thirst. The “living water” (John 4:10) of which Christ spoke was, of course, symbolic of the salvation He would provide. The waters of Eden (Genesis 2:10) and the New Jerusalem (Revelation 22:1) also speak of this.
