'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.

And the open spaces of the town will be full of boys and girls playing in its open spaces.

Let your doors be open, O Lebanon, so that fire may be burning among your cedars.

In that day, says the Lord, I will put fear into every horse and make every horseman go off his head: and my eyes will be open on the people of Judah, and I will make every horse of the peoples blind.

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.
