John 8:3,4 - Joseph Benson’s Commentary on the Old and New Testaments

And the scribes and Pharisees brought unto him a woman, &c. While he was thus employed, the scribes and Pharisees set a woman before him, that had been taken in the act of adultery; and standing round him, desired his opinion of the affair, which, it appears from John 8:6, they did with an insidious intention. “Probably,” says Dr. Macknight, “the Romans had modelled the laws of Judea according to the jurisprudence of Rome, and in particular had mitigated the severity of the punishment of the adulteress. Wherefore, if Jesus should say that the law of Moses ought to be executed upon this adulteress, the Pharisees hoped the people would stone her immediately, which would afford them an opportunity of accusing him before the governor, as a mover of sedition. But, if he should determine that the innovations practised by the Romans in such cases should take place, they resolved to represent him to the people as one who made void the law out of complaisance to their heathen masters. This their craft and wickedness Jesus fully knew, and regulated his conduct towards these depraved hypocrites accordingly, for he made them no answer.”
