Let there not be found among you that maketh his son or his daughter go through fire, either a bruterer or a maker of dismal days, or that useth witchcraft, or a sorcerer,

For these nations which thou shalt conquer hearken unto makers of dismal days and bruterers. But the LORD thy God permitteth not that to thee.
