'Opened' in the Bible

When Daniel learned that the document had been signed, he went into his house. The windows in its upper room opened toward Jerusalem, and three times a day he got down on his knees, prayed, and gave thanks to his God, just as he had done before.

A fiery stream issued and came forth from before him: thousand thousands ministered unto him, and ten thousand times ten thousand stood before him: the judgment was set, and the books were opened.

And, behold, one like the similitude of the sons of men touched my lips: then I opened my mouth, and spake, and said unto him that stood before me, O my lord, by the vision my sorrows are turned upon me, and I have retained no strength.
