Matthew 23:30

30 and you claim that if you had lived during the time of your ancestors, you would not have done what they did and killed the prophets.

Matthew 23:30 Meaning and Commentary

Matthew 23:30

And say, if we had been in the days of our fathers
Their ancestors and predecessors: signifying, that if they had lived in the times they did, or had been in the same post and office with them, they should have opposed, at least not consented to their measures: we would not have been partakers with them in the blood of the
prophets;
would not have joined them in persecuting the prophets, and in shedding their blood, and putting them to death; but would have received them as the prophets of the Lord, have hearkened to their advice and message, and have honoured and obeyed them as such; and this they thought they sufficiently declared, by building and adorning their tombs.

Matthew 23:30 In-Context

28 In the same way, on the outside you appear good to everybody, but inside you are full of hypocrisy and sins.
29 "How terrible for you, teachers of the Law and Pharisees! You hypocrites! You make fine tombs for the prophets and decorate the monuments of those who lived good lives;
30 and you claim that if you had lived during the time of your ancestors, you would not have done what they did and killed the prophets.
31 So you actually admit that you are the descendants of those who murdered the prophets!
32 Go on, then, and finish up what your ancestors started!
