'Open' in the Bible

When Daniel knew that the writing was signed, he went into his house (now his windows were open in his room toward Jerusalem) and he kneeled on his knees three times a day, and prayed, and gave thanks before his God, as he did before.

My God, turn your ear, and hear; open your eyes, and see our desolations, and the city which is called by your name: for we do not present our petitions before you for our righteousness, but for your great mercies' sake.
