'Open' in the Bible

This is what the Lord of armies has said: There will again be old men and old women seated in the open spaces of Jerusalem, every man with his stick in his hand because he is so old.

The city parks will be filled with boys and girls. They will play in the city's open parks.'

Open thy doors, O Lebanon, that the fire may devour thy cedars.

In that day, saith the LORD, I will smite every horse with astonishment, and his rider with madness: and I will open mine eyes upon the house of Judah, and will smite every horse of the people with blindness.

In that day there will be a fountain open to the family of David and to the people of Jerusalem, for sin and for that which is unclean.
