'Door' in the Bible

And the two folding-doors were of cypress-wood: the two leaves of the one door were folding, and the two leaves of the other door were folding.

And it was so, when Ahijah heard the sound of her feet, as she came in at the door, that he said, Come in, thou wife of Jeroboam; why feignest thou to be another? But I am sent to thee with a hard message.

And Jeroboam's wife arose and departed, and came to Tirzah; when she came to the threshold of the door, the child died.
