The vast mixed multitude of non - Israelites were present when the Law was inaugurated in 1513 B.C.E., but their firstborn were not taken into account when the Levites were taken as an exchange for the firstborn of Israel.
Suur hulk mitteiisraellastest segarahvast viibis juures, kui Seadus aastal 1513 e.m.a. anti, kuid nende esmasündinuid ei võetud arvesse, kui Iisraeli esmasündinud leviitidega lunastati.
