Titus 3:9 - Matthew Poole's English Annotations on the Holy Bible

But avoid foolish questions; in the discharge of thy ministry meddle not with idle questions, 2 Timothy 2:23, tending to no godly edifying. And genealogies; and sifting out genealogies, 1 Timothy 1:4. And contentions; and strifes about words, or things unprofitable; perverse disputings, and oppositions of science falsely so called, 1 Timothy 6:4,5,20. And strivings about the law; particularly questions about the law, the traditions and constitutions of the elders about it. For they are unprofitable and vain; these things are to no purpose or advantage.
