Zechariah 1:10

And the man answered - To the question addressed to the attendant-angel. He himself took the word.

These are they whom the Lord sent to walk up and down - Satan says of himself that he came “from going to and fro in the earth and from walking up and down in it” Job 2:2. As he for evil, so these for good. Their office was not a specific or passing duty, as when God sent His angels with some special commission, such as those recorded in Holy Scripture. It was a continuous conversation with the affairs of people, a minute course of visiting, inspecting our human deeds and ways, a part of the “wonderful order” , in which God has “ordained and constituted the services of angels and men.” Nor is it said that the angels were limited, each to his own special province, as we learn through Daniel, that certain great angels, princes among them, had the charge of empires or nations, even of the pagan . These angels had apparently only the office of inspecting and reporting to angels of a higher order, themselves a subordinate order in the heavenly Hierarchy. Nor are they spoken of, as executing any judgments of God, or as pacifying the earth; they may have been so employed; but they are only said to have reported the state in which they found it.

These answered the unexpressed inquiry of the angel of the Lord, as he had answered the unuttered question of the angel, attendant on Zechariah.
