Bede : When he came, he conferred much with those who believed. For he vigorously confuted the Jews. Another translation has: He greatly benefited the believers by grace. This is what the Apostle writes to the Achaians: "I planted, Apollos watered" (I Cor. III). — Commentary on Acts John Chrysostom : "And when he was disposed to pass into Achaia, the brethren wrote, exhorting the disciples to receive him." He wished then also to depart into Achaia, and these also encouraged him to do so, having also given him letters. In faith, he did all by faith; "the brethren wrote," etc. Nowhere envy, nowhere an evil eye. Aquila teaches, or rather this man lets himself be taught. He was minded to depart, and they send letters. — Homily on Acts 40
