John Gill Commentary Luke 20:3

"And he answered and said unto them, I also will ask you a question; and tell me:" — Luke 20:3 (ASV)

I will also ask you one thing, and answer me ;
when he also promised, that if they would give him an answer to his question, he would satisfy them in the point they interrogated him about: and as this was a prudent decline to avoid the snare they laid for him, so it was not an impertinent reply to them; since it led on to a proper answer to their question, as appears by the case proposed; (See Gill on Matthew 21:24).
