Impurity does not enter a shelter, nor does it depart from it if there is an opening less than a handbreadth by a handbreadth.

What is implied? When there is a window between one house and another or between a house and a loft, if it is a square handbreadth by a handbreadth and there was impurity in one of the structures, the other structure is also impure. If the window does not comprise a handbreadth by a handbreadth, impurity does not depart from it, nor does it enter the second structure.

When does the above apply? With regard to a window made by a person for functional purposes. When, by contrast, a window was made by man for illumination, that light should enter, its measure is the size of pundiyon. Then ritual impurity departs through it.

What is implied? There was impurity in a house. A person came and stood on the outside, near this window for light or placed a k'li there, or there was a covering on the other side of the wall, the person, the k'li, and everything under the covering to which the impurity passes through becomes impure. A window made for light is one that is not covered by a roof, but instead, is open to the sun.

When an aperture was not made through intentional human activity, e.g., it was hollowed out by water or crawling animals, the earth itself cratered, a window had been shuttered close and the shutter was removed, or it had been covered by glass and the glass broke, the minimum measure is the full span of a shingle which is the size of the head of an ordinary man.

The above applies provided that the owner did not think of using that aperture for functional purposes. If, however, he thought of using it, the minimum measure is an opening of a handbreadth by a handbreadth. If he thought to use it for light, its measure is the size of a pundiyon. The rationale is that, in these instances, thought is considered equivalent to deed.

The following rules apply when a person began closing a window opened for light and did not complete the task because he did not have sufficient cement or a colleague called him, night fell initiating the Sabbath, and there remained a small amount open. If a portion the height of two fingerbreadths and the width of a thumbbreadth remain, it conveys ritual impurity. If it is less than that, it is as if it was closed.

The following rules apply when there was a large window made for light covered by a lattice or the like. If there was one place where there is a hole as large as a pundiyon, it conveys ritual impurity and allows ritual impurity to depart. If the holes of the lattice are small and not one of them is the size of a pundiyon, it is considered as closed. Similarly, when there was a large window made for functional purposes and it was covered by thatchwork coverings or shades, if there was empty space a handbreadth by a handbreadth square, it conveys ritual impurity and allows ritual impurity to depart. Otherwise, it is considered as closed.

When a window is exposed to the open air, its minimum measure is the size of a pundiyon, because it is made solely for the purpose of light, as we explained. If one builds a house outside this window and thus the window is now under a roof, it is considered as if it is between two structures and its measure is a handbreadth by a handbreadth of empty space. If the roof was built in the middle of the window, the measure for the lower portion that is below the roof is a handbreadth by a handbreadth of empty space. The measure of the upper portion that is above the roof is the size of a pundiyon, because it is exposed to the open air.

The following rules apply in the situations to be described: There is a hole in a door, a carpenter left an empty place above or below or hung two swinging doors and did not complete adjusting them and thus there was empty space between the two doors, or he closed the door and it was blown open by the wind. In all these situations, if the opening was the size of a shingle, the impurity leaves through this opening and enters through it. If the opening is less than the size of a shingle, it is considered as closed.

When a person makes a hole in a wall in order to place a rod or a large nail there, to see those who pass by, or to speak to his colleague, it is considered as a window made for functional purposes and its minimum measure is a space a handbreadth by a handbreadth.
