SEV Biblia, Chapter 31:19
Y vosotros quedaos fuera del campamento siete días; y todos los que hubieren matado persona, y cualquiera que hubiere tocado muerto, os expiaréis al tercero y al séptimo día, vosotros y vuestros cautivos.
John Gill's Bible Commentary
Ver. 19. And do ye abide without the camp seven days . etc.] Which was the time that anyone that touched a dead body remained unclean, ( Numbers 19:11), whosoever hath killed any person ; as most of them if not all must have done; all the males of Midian that fell into their hands being slain by them, that were men grown: and whosoever hath touched any slain ; as they must to strip them of their garments, and take their spoil from them: purify both yourselves and your captives, on the third and on the seventh day ; which were the days appointed for the purification of such that were polluted by touching dead bodies, ( Numbers 19:11) and their captives, which were the female little ones; (for as for the women, and males among the little ones, they were ordered to be slain;) though they were Heathens, yet inasmuch as they were to be for the service of the Israelites, and to be brought up in their religion, they were to be purified also; to which purpose is the note of Jarchi; “not that the Gentiles receive uncleanness and need sprinkling, but as ye are the children of the covenant, so your captives, when they come into the covenant, and are defiled, need sprinkling.”
Matthew Henry Commentary
Verses 19-24 - The Israelites had to purify themselves according to the law, and to abide without the camp seven days, though they had not contracted an moral guilt, the war being just and lawful, and commanded by God. Thu God would preserve in their minds a dread and detestation of sheddin blood. The spoil had been used by Midianites, and being now come int the possession of Israelites, it was fit that it should be purified.
