Forbear to cry, make no mourning for the dead, bind the tire of thine head upon thee, and put on thy shoes upon thy feet, and cover not thy lips, and eat not the bread of men. Make no mourning - As a priest, he could make no public mourning, Leviticus 21:1, etc.
Bind the tire of thine head - This seems to refer to the high priest's bonnet; or perhaps, one worn by the ordinary priests: it might have been a black veil to cover the head.
Put on thy shoes upon thy feet - Walking barefoot was a sign of grief.
Cover not thy lips - Mourners covered the under part of the face, from the nose to the bottom of the chin.
Eat not the bread of men - לחם אנשים lechem anashim, "the bread of miserable men," i.e., mourners; probably, the funeral banquet.
