Numbers 19:19-20

ECB(i) 19 and the pure sprinkles on the foul on the third day and on the seventh day: and on the seventh day he sacrifices for his sin and launders his clothes and baptizes in water and purifies at evening. 20 And the man who becomes foul and purifies not for his sin, that soul becomes cut off midst the congregation because he fouled the holies of Yah Veh: the water of exclusion not being sprinkled on him - he is foul.
