'Standing' in the Bible

I looked out in the night and saw a man riding on a red horse. He was standing among the myrtle trees in the valley. Behind him were red, sorrel, and white horses.

Then the man standing among the myrtle trees explained, “They are the ones the Lord has sent to patrol the earth.”

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

So the Angel of the Lord spoke to those standing before Him, “Take off his filthy clothes!” Then He said to him, “See, I have removed your guilt from you, and I will clothe you with splendid robes.”

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.

“This is what the Lord of Hosts says: If you walk in My ways and keep My instructions, you will both rule My house and take care of My courts; I will also grant you access among these who are standing here.
