Matthew Poole and continuators on John 1:28

28 These things were done in Bethabara beyond Jordan , where John was Baptizing .

The Evangelist had before told us what was done, these words tell us where. Some ancient Writers will have the place to have been Bethany; but they seem not to have so well considered Iohn 11.18. where Bethany is said to have been but fifteen Furlongs from Ierusalem, and consequently on this side Iordan; whereas the Evangelist saith, that this place was [non-Latin text not transcribed], beyond Iordan, in the Tribe of Reuben, in the Country of Peraea,

where Iohn at this time was Baptizing, and probably had been so for some time.
