'Executing' in the Bible

I persecuted this Way, even executing people, and kept tying up both men and women and putting them in prison,

with the power of signs and wonders, [and all of it] in the power of the Spirit. So [starting] from Jerusalem and as far away as Illyricum, I have fully preached the gospel [faithfully preaching the good news] of Christ [where it had not before been preached].
