Mark 10:3

And he answered and said unto them
Very prudently and wisely,

what did Moses command you?
according to Matthew, he put another question to them; see ( Matthew 19:4 ) ; no doubt but both were put, and this after they had urged the authority and law of Moses: and therefore be very pertinently asks them, what Moses had said about divorces, what law he had left; and puts them upon producing and repeating it, that the sense of it might be examined, and it be considered, upon what account it was given.
