22 H310 And after H935 that went H3881 the Levites H5647 in to do H5656 their service H168 in the tabernacle H4150 of the congregation H6440 before H175 Aaron, H6440 and before H1121 his sons: H3068 as the LORD H6680 had commanded H4872 Moses H5921 concerning H3881 the Levites, H3651 so H6213 did they to them.

23 H3068 And the LORD H1696 spoke H4872 to Moses, H559 saying,

24 H2063 This H3881 is it that belongs to the Levites: H6242 from twenty H2568 and five H8141 years H1121 old H4605 and upward H935 they shall go H6633 in to wait H5656 on the service H168 of the tabernacle H4150 of the congregation:

25 H1121 And from the age H2572 of fifty H8141 years H7725 they shall cease H6635 waiting H5656 on the service H5647 thereof, and shall serve H3808 no H5750 more:

26 H8334 But shall minister H251 with their brothers H168 in the tabernacle H4150 of the congregation, H8104 to keep H4931 the charge, H5647 and shall do H3808 no H5656 service. H3602 Thus H6213 shall you do H3881 to the Levites H4931 touching their charge.
