Matthew Poole and continuators on John 4:6

6 Now Jacobs well was there . Jesus therefore being wearied with his journey, sat thus on the well : and it was about the sixth hour .

It was called Iacobs, either because he digged it, (as we read of Abrahams digging a well, Gen. 21.30▪ and Isaac, Gen. 26.15.) or because he and his Family used it, as Verse 12.

Our Lord used no Horse, or Chariot ordinarily in his Travels, but went on foot; we never read of him in a Coach or Chariot, but once upon the back of a beast, (that was when he rode into Hierusalem upon an Ass) he ordinarily travelled on foot; and the Evangelist taketh notice of his weariness, to let us know that he was truly Man, and subjected to weariness, and other humane infirmities; and he rested himself upon the sides of the Well

and it was about Noon-time: For that was according to their computation, the sixth hour. The 8th Verse tells us, His Disciples were gone to the City to buy Meat, so as he was alone.
