'Beside' in the Bible

Then I said, "Let them place a pure diadem on his head." So they placed the pure diadem on his head and clothed him with fine garments while the angel of the LORD was standing beside them.

There are also two olive trees beside it, one on the right of the bowl and the other on its left.”

And I questioned him further, “What are the two olive branches beside the two gold conduits, from which golden oil pours out?”

He said, "These are the two anointed ones, who stand continuously beside the Lord of the whole earth."
