'Angel of the Lord' in the Bible

They reported to the Angel of the Lord standing among the myrtle trees, “We have patrolled the earth, and right now the whole earth is calm and quiet.”

Then the Angel of the Lord responded, “How long, Lord of Hosts, will You withhold mercy from Jerusalem and the cities of Judah that You have been angry with these 70 years?”

Then he showed me Joshua the high priest standing before the Angel of the Lord, with Satan standing at his right side to accuse him.

Then I said, “Let them put a clean turban on his head.” So a clean turban was placed on his head, and they clothed him in garments while the Angel of the Lord was standing nearby.

Then the Angel of the Lord charged Joshua:

On that day the Lord will defend the inhabitants of Jerusalem, so that on that day the one who is weakest among them will be like David on that day, and the house of David will be like God, like the Angel of the Lord, before them.
