333. Where did John baptize?

In the Jordan River

And the same John had his raiment of camel's hair, and a leathern girdle about his loins; and his meat was locusts and wild honey. Then went out to him Jerusalem, and all Judaea, and all the region round about Jordan, And were baptized of him in Jordan, confessing their sins. Matthew 3:4-6

And it came to pass in those days, that Jesus came from Nazareth of Galilee, and was baptized of John in Jordan. Mark 1:9

In Bethabara, beyond the Jordan

These things were done in Bethabara beyond Jordan, where John was baptizing. John 1:28
