Expositor's Bible Commentary Commentary Acts 22:5

"As also the high priest doth bear me witness, and all the estate of the elders: from whom also I received letters unto the brethren, and journeyed to Damascus to bring them also that were there unto Jerusalem in bonds to be punished." — Acts 22:5 (ASV)

As evidence of his zeal for God and the Jewish religion, Paul cites his earlier persecution of Christians (cf. comments on 9:1–2). The ascription “this way” picks up what was the earliest self-designation of the first believers in Jesus at Jerusalem—namely, “those of the Way” (cf. comment on 9:2).
