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 vosoutros vos alojai sete dias fora do arraial: qualquer que tiver matado algum homem, e qualquer que tiver tocado a algum morto, ao terceiro dia, e ao setimo dia vos expiareis, a vós e a vossos presioneiros.
