Wherefore ye witness to yourselves, that ye are sons of them that slew the prophets.

So that you are witnesses against yourselves that you are the sons of those who put the prophets to death.

Ωστε μαρτυρειτε εις εαυτους οτι εισθε υιοι των φονευσαντων τους προφητας.

Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets.
