SEV Biblia, Chapter 31:20
Asimismo expiaréis todo vestido, y toda prenda de pieles, y toda obra de pelos de cabra, y todo vaso de madera.
John Gill's Bible Commentary
Ver. 20. And purify all your raiment , etc.] By washing them; and this may intend not so much their own wearing apparel, as the raiment they took off of the dead bodies of the Midianites, since the person that touched a dead body was not obliged to wash his clothes, but the clean person that sprinkled the water of purification on him, ( Numbers 19:19,21), some render the words, “purify yourselves” f456 , “together with the raiment”, etc. which seems to be the best version of them: and all that is made of skins ; of any sort of creatures, as the covering of tents, shoes, bottles, etc. (see Leviticus 11:32) and all work of goats’ hair ; such as the covering of tents was also made of: and this, according to Jarchi and other Jewish writers includes vessels made of the horns, hoofs, and bones of these creatures: and all things made of wood; as beds, cups, dishes, etc. all which might be purified by washing; (see Leviticus 15:12).
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.
