Num 31:21-24 To this end Eleazar, whose duty it was as high priest to see that the laws of purification were properly observed, issued fuller instructions with reference to the purification of the different articles, in accordance with the law in ch. 19. למּלחמה הבּאים, those who came to the war, i.e., who went into the battle (see at Num 10:9). “The ordinance of the law:” as in Num 19:2.
