JMNT(i)
2 Now within Jerusalem, at the sheep gate [which is within the northern city wall], there is a constructed pool [for bathing or swimming] – the one being normally called (or: named) in Hebrew "Bethzatha" (means: House of the Olive; [other MSS: Bethesda, which means: House of Mercy]) – presently having five covered colonnades (porticos; porches supported by columns). [note: that this structure existed when John wrote this (the verb is present tense) is evidence for this being written prior to A.D. 70 and the destruction of Jerusalem]
