'Surround' in the Bible

So he said to the people of Judah, “Let’s build these cities and surround them with walls and towers, with doors and bars. The land is still ours because we sought the Lord our God. We sought Him and He gave us rest on every side.” So they built and succeeded.

You must completely surround the king with weapons in hand. Anyone who enters the temple is to be put to death. You must be with the king in all his daily tasks.”
