the two jaw-bones are located at the bottom of the face, one on the right and one on the left, and the chin is where they meet. The beard hair is part of the face and must therefore be washed, even if it is long. If the beard is thin, both its inner side and its outer side must be washed; if it is thick—meaning that it covers the skin—only the outside is obligatory, although running the fingers through the inside is recommended, as noted earlier. The width of the face extends from ear to ear, and the ears are considered part of the head, so they are wiped along with it, as mentioned above.

He then washes his arms, including the elbows, three times. The arm in this context extends from the fingertips, nails included, up to the beginning of the upper arm. Anything stuck to the hands that would prevent the water from reaching the skin—such as dough, mud, or a thick layer of dye or nail polish—must be removed before washing.

Next he wipes his entire head and his ears once with fresh water, not merely with the moisture left from washing his arms. To wipe the head, he places his wet hands on the front of the head, passes them back to the nape, and then returns them to the spot where he began. He then inserts his index fingers into the inner folds of the ears and wipes their outer surfaces with his thumbs.

Finally, he washes his feet three times, including the ankles. The ankles are the two protruding bones at the bottom of the leg.
