48 "Really (or: Consequently; Accordingly then), you folks exist being witnesses (or: continuously are folks who testify and give evidence) and you are constantly approving, thinking well of and giving endorsement to the actions (deeds; works) of your fathers (and: forefathers), because they indeed killed them off, and now you yourselves continue building the [memorial] houses [other MSS: their tombs]!
49 "That is why (or: On account of this) the Wisdom of God also said, 'As emissaries I will proceed sending off prophets and representatives unto them (or: into the midst of them) – and they will proceed killing off [some] from out of their midst, and then they will proceed to pursue (chase; press forward [on] and persecute; [other MSS: banish]) [others],'
50 "So thus, the blood of all of the prophets – that having been [other MSS: being constantly or repeatedly] poured out from the casting down (the founding; the foundation; or: may = the conceiving) of [the] ordered system (world of culture, economy, religion and government) – can (or: should; would) at some point (or: suddenly) be searched out to be required and exacted from this generation:
51 "from Abel's blood until the blood of Zechariah – the man losing himself (or: perishing; being destroyed) between the altar and the House – yes, I continue saying (or: am now saying) to you folks, it will progressively be sought out and exacted from this generation.
