'Closed' in the Bible

Pharaoh will say about the Israelis, "They're wandering aimlessly in the land, and the desert has closed in on them.'

But if the ox has tried to gore on a previous occasion, and its owner has been warned, but has not kept it confined and it kills a man or a woman, the ox shall be stoned and its owner shall be put to death as well.

Or if it is known that the ox was previously in the habit of goring, and its owner has not kept it confined, he must make restitution of ox for ox, and the dead [animal] shall be his.

You shall join five curtains by themselves and the other six curtains by themselves, and you shall double over the sixth curtain at the front of the tent [to make a closed door].
