Adam Clarke on Acts 18:26

They took him unto them - This eloquent man, and mighty in the Scriptures, who was even a public teacher, was not ashamed to be indebted to the instructions of a Christian woman, in matters that not only concerned his own salvation, but also the work of the ministry, in which he was engaged. It is disgraceful to a man to be ignorant, when he may acquire wisdom; but it is no disgrace to acquire wisdom from the meanest person or thing. The adage is good: Despise not advice, even of the meanest: the gaggling of geese preserved the Roman state.
