4. They made no conscience of what they said and what they did in the most solemn manner, v. 4 (1.) Not of what they said in swearing, which is the most solemn speaking: They have spoken words, and words only, for they meant not as they said; they did verba dare—give words. They swore falsely in making a covenant; they were deceitful in their covenanting with God, the covenant of circumcision, the fair promises they made of reformation when they were in distress; and no marvel if those that were false to their God were false to all mankind. They contracted such a habit of treachery that they broke through the most sacred bonds, and made nothing of them; subjects violated their oaths of allegiance and their kings their coronation-oaths; they broke their leagues with the nations they were in alliance with, nor was any conscience made of contracts between private persons. (2.) Nor of what they did in judgment, which is the most solemn acting. Justice could not take place when men made nothing of forswearing themselves; for thus judgment, which should have been a healing medicinal plant and of a sweet smell, sprang up as hemlock, which is both nauseous and noxious, in the furrows of the field, in the field that was ploughed and furrowed for good corn. Note, God is greatly offended with corruptions, not only in his own worship, but in the administration of justice between man and man, and the dishonesty of a people shall be the ground of his controversy with them as well as their idolatry and impiety; for God's laws are intended for man's benefit and the good of the community, as well as for God's honour, and the profanation of courts of justice shall be avenged as surely as the profanation of temples.
