STEADFASTNESS & TRUE JUSTICE: Zachary and Elizabeth are models of steadfastness in what is right. They lived in an evil time when most of the Israelites, and even most of the priests, had grown lax in the service of God, and no longer worshiped Him in their hearts. But in spite of the evil example of those around them, Zachary and Elizabeth remained true to God, and faithfully observed His commandments. Zachary and Elizabeth were not only just in the eyes of men, as were the hypocritical Pharisees, but were "just before God."
