04:008:018 And I have taken the Levites for all the firstborn of the
           children of Israel.

04:008:019 And I have given the Levites as a gift to Aaron and to his
           sons from among the children of Israel, to do the service of
           the children of Israel in the tabernacle of the congregation,
           and to make an atonement for the children of Israel:  that
           there be no plague among the children of Israel, when the
           children of Israel come nigh unto the sanctuary.

04:008:020 And Moses, and Aaron, and all the congregation of the children
           of Israel, did to the Levites according unto all that the lord
           commanded Moses concerning the Levites, so did the children of
           Israel unto them.

04:008:021 And the Levites were purified, and they washed their clothes;
           and Aaron offered them as an offering before the lord; and
           Aaron made an atonement for them to cleanse them.

04:008:022 And after that went the Levites in to do their service in the
           tabernacle of the congregation before Aaron, and before his
           sons:  as the lord had commanded Moses concerning the Levites,
           so did they unto them.

04:008:023 And the lord spake unto Moses, saying,

04:008:024 This is it that belongeth unto the Levites:  from twenty and
           five years old and upward they shall go in to wait upon the
           service of the tabernacle of the congregation: 

04:008:025 And from the age of fifty years they shall cease waiting upon
           the service thereof, and shall serve no more: 

04:008:026 But shall minister with their brethren in the tabernacle of
           the congregation, to keep the charge, and shall do no service. 
           Thus shalt thou do unto the Levites touching their charge.

04:009:001 And the lord spake unto Moses in the wilderness of Sinai, in
           the first month of the second year after they were come out of
           the land of Egypt, saying,

04:009:002 Let the children of Israel also keep the passover at his
           appointed season.

04:009:003 In the fourteenth day of this month, at even, ye shall keep it
           in his appointed season:  according to all the rites of it, and
           according to all the ceremonies thereof, shall ye keep it.

04:009:004 And Moses spake unto the children of Israel, that they should
           keep the passover.

04:009:005 And they kept the passover on the fourteenth day of the first
           month at even in the wilderness of Sinai:  according to all
           that the lord commanded Moses, so did the children of Israel.

04:009:006 And there were certain men, who were defiled by the dead body
           of a man, that they could not keep the passover on that day: 
           and they came before Moses and before Aaron on that day:
