Números 31:19

19 "Anyone who has killed someone or touched someone who was killed must stay outside the camp seven days. On the third and seventh days you must purify yourselves and your captives.

19 E, vós, alojai-vos sete dias fora do arraial; qualquer que tiver matado alguma pessoa e qualquer que tiver tocado algum morto, ao terceiro dia e ao sétimo dia, vos purificareis, a vós e a vossos cativos.
