  24 H4643 But the tithes H1121 of the sons H3478 of Israel, H7311 [H8686] which they offer H8641 as an heave offering H3068 to the LORD, H5414 [H8804] I have given H3881 to the Levites H5159 to inherit: H559 [H8804] therefore I have said H8432 to them, Among H1121 the sons H3478 of Israel H5157 [H8799] they shall have H5159 no inheritance.
  25 H3068 And the LORD H1696 [H8762] spoke H4872 to Moses, H559 [H8800] saying,
  26 H1696 [H8762] Thus speak H3881 to the Levites, H559 [H8804] and say H3947 [H8799] to them, When ye take H1121 of the sons H3478 of Israel H4643 the tithes H5414 [H8804] which I have given H5159 you from them for your inheritance, H7311 [H8689] then ye shall offer H8641 up an heave offering H3068 of it for the LORD, H4643 even a tenth H4643 part of the tithe.
  27 H8641 And this your heave offering H2803 [H8738] shall be reckoned H1715 to you, as though it were the grain H1637 of the threshingfloor, H4395 and as the fulness H3342 of the winepress.
  28 H7311 [H8686] Thus ye also shall offer H8641 an heave offering H3068 to the LORD H4643 of all your tithes, H3947 [H8799] which ye receive H1121 of the sons H3478 of Israel; H5414 [H8804] and ye shall give H3068 of them the LORD'S H8641 heave offering H175 to Aaron H3548 the priest.
