10. As they dealt deceitfully with God by seeking answers of peace without repentance, so God would let them be dealt with deceitfully by the prophets whom they consulted. God would chastise their sin with a corresponding sin; as they rejected the safe directions of the true light, He would send the pernicious delusions of a false one; prophets would be given them who should re-echo the deceitfulness that already wrought in their own bosom, to their ruin [FAIRBAIRN]. The people had themselves alone to blame, for they were long ago forewarned how to discern and to treat a false prophet (De 13:3); the very existence of such deceivers among them was a sign of God's judicial displeasure (compare in Saul's case, 1Sa 16:14; 28:6, 7). They and the prophet, being dupes of a common delusion, should be involved in a common ruin.
