Albert Barnes Commentary Acts 22:4

"and I persecuted this Way unto the death, binding and delivering into prisons both men and women." — Acts 22:4 (ASV)

And I persecuted (Acts 8:3).

This way. This refers to those who worshipped God in this way; that is, Christians (see Barnes on Acts 9:2).

Unto the death. Intending to put them to death, he probably did not put anyone to death himself. Instead, he committed them to prison, sought their lives, and was the agent employed in arresting them. And when they were put to death, he tells us that he gave his voice against them (Acts 26:10); that is, he joined in and approved of their condemnation.

Delivering into prisons, etc. (Acts 8:3).
