Leviticus 19:26-28

‘You shall not eat anything with the blood, nor practice divination [using omens or witchcraft] or soothsaying. You shall not trim and round off the side-growth of [the hair on] your heads, nor mar the edges of your beard. You shall not make any cuts on your body [in mourning] for the dead, nor make any tattoo marks on yourselves; I am the LORD.
