Chapter 4:1-6 Jesus Goes to Galilee

4:1 When therefore the Lord knew how the Pharisees had heard that Jesus made and baptized more disciples than John,
The Lord knew - Though none informed Him of it.

4:2 (Though Jesus Himself baptized not, but His disciples,)

Though Jesus Himself baptized not - it was a false report that was made to the Pharisees.

4:3 He left Judaea, and departed again into Galilee.

He left Judaea - Where he had been for some time: at the feast of the passover he went up to Jerusalem, and after a short stay there, he came into the country part of Judea, where he tarried longer; and in both about the space of eight months; for it was now but four months to harvest, which began at the passover; ; see John 2:13.

4:4 And He must needs go through Samaria.

And He must needs go through Samaria - The road lying directly through it.

4:5 Then cometh He to a city of Samaria, which is called Sychar, near to the parcel of ground that Jacob gave to his son Joseph.

Sychar - Formerly called Sichem or Shechem. Jacob gave - On his death bed.

4:6 Now Jacob's well was there. Jesus therefore, being wearied with His journey, sat thus on the well: and it was about the sixth hour.

Now Jacob's well was there - So called, either because it was dug by him; or because he and his family made use of it, when in those parts. 

Jesus therefore being wearied with His journey; having travelled on foot, from Judea thither; and he having a body like to ours, subject to weariness. 

and it was about the sixth hour; about twelve o'clock at noon.
