5 And I heard the Agent of the Waters saying, "You are continually a Just One (a Righteous One; One Who observes the way pointed out), the One continuously existing (or: being), even the One Who was continuously existing, the appropriately pious, sanctioned, benign One, because You suddenly judge (or: judged) these,
6 "because they poured (or: pour) out [the] blood of the set-apart folks and of the prophets, and You gave (or: give) them blood to drink: they are deserving [this]!" [note: see Luke 11:50-51]
