“You testify

Against yourselves.

You are descendants

Of those

Who murdered

The prophets.

Fill up,

Then,

The measure

Of your ancestors!”

 

ὥστε μαρτυρεῖτε ἑαυτοῖς ὅτι υἱοί ἐστε τῶν φονευσάντων τοὺς προφήτας

καὶ ὑμεῖς πληρώσατε τὸ μέτρον τῶν πατέρων ὑμῶν.

 

There is something similar in Luke, chapter 11:48.  The Pharisees and Scribes testified or witnessed against themselves (ὥστε μαρτυρεῖτε ἑαυτοῖς), since they admitted that they were the descendants or sons of those who murdered the prophets (ὅτι υἱοί ἐστε τῶν φονευσάντων τοὺς προφήτας).  Jesus then told them to fill up or complete the work with the measuring rod of their ancestors (καὶ ὑμεῖς πληρώσατε τὸ μέτρον τῶν πατέρων ὑμῶν).   Thus, they have the same attitude as their ancestors.  However, there is very little evidence of Jewish prophets being killed.
