Joshua - Chapter 4

We have in this chapter the long anticipated crossing of the river Jordan as the people enter the promised land.  Joshua was told by God to place stones at the site of the crossing as a memorial, to remind people of God's miracle.

When John the Baptist was baptising in the river Jordan he was at Bethbara - "the house of passage" - which is thought to be the site of the crossing.  

"Then Jerusalem, all Judea, and all the region around the Jordan went out to him and were baptized by him in the Jordan, confessing their sins.  But when he saw many of the Pharisees and Sadducees coming to his baptism, he said to them, “Brood of vipers! Who warned you to flee from the wrath to come? Therefore bear fruits worthy of repentance, and do not think to say to yourselves, ‘We have Abraham as our father.’ For I say to you that God is able to raise up children to Abraham from these stones."

The stones that John is pointing to are possibly the memorial stones from Joshua's crossing.

And this is the location of Jesus' baptism by John at the start of his ministry.
