The Pool of Bethesda
GradeProbable
John describes "a pool, which is called in the Hebrew tongue Bethesda, having five porches" by the sheep market in Jerusalem (). Twin pools have been excavated near the Church of St Anne, by the Lions' Gate, with phases from the Second Temple period (they are said to have been expanded about 200 BCE) and later Byzantine and Crusader building. Two pools fit John's "five porches": colonnades on four sides and one along the dividing wall. The Copper Scroll from Qumran may name a "Beth Eshdatayin". As with Siloam, Christians point out that John knew a particular Jerusalem site from before 70, of a kind a distant or late writer would be unlikely to know.
Probable. The pools are authentic and have Second Temple phases; their identification with John's Bethesda is likely but not certain. Until the 19th century there was no clear archaeological evidence that such a pool existed.

The details of the colonnades are debated, so the fit with "five porches" is not settled, and the Copper Scroll reading is itself uncertain. Like Siloam, the site would confirm John's knowledge of the setting, not the healing he reports there.
