'Opened' in the Bible

I said to them, "Don't let the gates of Jerusalem be opened until the sun is hot; and while they stand guard, let them shut the doors, and you bar them: and appoint watches of the inhabitants of Jerusalem, everyone in his watch, with everyone near his house."

Ezra opened the book in the sight of all the people; (for he was above all the people;) and when he opened it, all the people stood up:

It came to pass that, when the gates of Jerusalem began to be dark before the Sabbath, I commanded that the doors should be shut, and commanded that they should not be opened until after the Sabbath. I set some of my servants over the gates, that no burden should be brought in on the Sabbath day.
