Isaiah 33:18

Thine heart — This is a thankful acknowledgment of deliverance from their former terrors and miseries. Where — These words they spoke in the time of their distress. The scribe, whom we call muster — master, was to make and keep a list of the soldiers, and to call them together as occasion required: the receiver, received and laid out the money for the charges of the war; and he that counted the towers, surveyed all the parts of the city, and considered what towers or fortifications were to be made or repaired. And unto these several officers the people resorted, with great distraction and confusion.
