Isaiah 1:6

From the sole of the foot even unto the head, that is, the whole body of the people, from the lowest to the highest and most honorable, there is no soundness in it, not a healthy spot, but wounds, gaping as from the stroke of a sword, and bruises, contusions as from the blows of fists, and putrefying sores, from which the pus must be drawn; they have not been closed, by pressing the gaping edges together, both to remove all foreign matter and to cause an even healing, neither bound up, by a cool and softening bandage, neither mollified with ointment, to hasten the healing process. In other words, when the prophets tried to heal the various wounds and bruises of Israel by using the knife of the Law, by calling the people to repentance, in order to apply the cooling ointment of the Gospel afterwards, the people resented the treatment and hindered the healing; they refused the assistance of the Lord and repudiated His mercy. The prophet now abandons his figurative language for a concrete description of the situation in Judah and Jerusalem at that time.
