God gives many laws regarding fairness and honesty, charity and kindness. God commands that the Israelites be holy for God has set them apart to be God s holy people. God then gives Moses the laws specific to Aaron and all the priests.
Priests are to stay pure and holy.
They are not to have contact with the dead, nor profane the Name of God, nor marry a harlot nor even marry a divorced person. When the daughter of a priest degrades herself through harlotry, it is her father whom she degrades and she must be burned in fire. The High Priest must abide by additional rules. He must not let his hair on his head grow wild. He must not tear his garments in mourning, nor have contact with the dead.
