'Heads' in the Bible

Moses said to Aaron, and to Eleazar and to Ithamar, his sons, "Don't let the hair of your heads go loose, neither tear your clothes; that you don't die, and that he not be angry with all the congregation: but let your brothers, the whole house of Israel, bewail the burning which Yahweh has kindled.

"'You shall not cut the hair on the sides of your heads, neither shall you clip off the edge of your beard.

"'They shall not shave their heads, neither shall they shave off the corners of their beards, nor make any cuttings in their flesh.
