Commentaries:
Robertson's Word Pictures (NT)
Was reading (aneginwsken). Imperfect active descriptive, not periphrastic like the two preceding verbs (was returning and sitting). He was reading aloud as Philip "heard him reading" (hkousen auton anaginwskontov), a common practice among orientals. He had probably purchased this roll of Isaiah in Jerusalem and was reading the LXX Greek text. See imperfect again in verse Acts 8:32.
