Leviticus

Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the Lord.

And they shall come at no dead person to defile themselves: but for father, or for mother, or for son, or for daughter, for brother, or for sister that hath had no husband, they may defile themselves.

Command the children of Israel, that they put out of the camp every leper, and every one that hath an issue, and whosoever is defiled by the dead:

He that toucheth the dead body of any man shall be unclean seven days.

I have not eaten thereof in my mourning, neither have I taken away ought thereof for any unclean use, nor given ought thereof for the dead: but I have hearkened to the voice of the Lord my God, and have done according to all that thou hast commanded me.
