AKJV_Strongs(i)
  21 H2009 And, behold, H5414 I have given H1121 the children H3878 of Levi H3605 all H4643 the tenth H3478 in Israel H5159 for an inheritance, H5656 for their service H834 which H5647 they serve, H5656 even the service H168 of the tabernacle H4150 of the congregation.
  22 H3808 Neither H1121 must the children H3478 of Israel H5750 from now on H7126 come H7126 near H168 the tabernacle H4150 of the congregation, H5375 lest they bear H2399 sin, H4191 and die.
  23 H3881 But the Levites H5647 shall do H5656 the service H168 of the tabernacle H4150 of the congregation, H5375 and they shall bear H5771 their iniquity: H2708 it shall be a statute H5769 for ever H1755 throughout your generations, H8432 that among H1121 the children H3478 of Israel H3808 they have no H5159 inheritance.
  24 H4643 But the tithes H1121 of the children H3478 of Israel, H834 which H7311 they offer H8641 as an heave H8641 offering H3068 to the LORD, H5414 I have given H3881 to the Levites H5159 to inherit: H5921 therefore H3651 H559 I have said H8432 to them, Among H1121 the children H3478 of Israel H3808 they shall have no H5159 inheritance.
  25 H3068 And the LORD H1696 spoke H4872 to Moses, H559 saying,
  26 H1696 Thus speak H3881 to the Levites, H559 and say H3588 to them, When H3947 you take H1121 of the children H3478 of Israel H4643 the tithes H834 which H5414 I have given H5159 you from them for your inheritance, H7311 then you shall offer H8641 up an heave H8641 offering H3068 of it for the LORD, H4643 even a tenth H2506 part H4643 of the tithe.
  27 H8641 And this your heave H8641 offering H2803 shall be reckoned H1715 to you, as though it were the corn H1637 of the threshing floor, H4395 and as the fullness H3342 of the wine press.
  28 H3651 Thus H1571 you also H7311 shall offer H8641 an heave H8641 offering H3068 to the LORD H3605 of all H4643 your tithes, H834 which H3947 you receive H1121 of the children H3478 of Israel; H5414 and you shall give H3068 thereof the LORD’s H8641 heave H8641 offering H175 to Aaron H3548 the priest.
