CKJV_Strongs(i)
  26 H1696 Thus speak H3881 unto the Levites, H559 and say H3947 unto them, When you take H1121 of the sons H3478 of Israel H4643 the tithes H5414 which I have given H5159 you from them for your inheritance, H7311 then you 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 shall be reckoned H1715 unto you, as though it were the corn H1637 of the threshingfloor, H4395 and as the fullness H3342 of the winepress.
  28 H7311 Thus you also shall offer H8641 an heave offering H3068 unto the Lord H4643 of all your tithes, H3947 which you receive H1121 of the sons H3478 of Israel; H5414 and you shall give H3068 there the Lord's H8641 heave offering H175 to Aaron H3548 the priest.
  29 H4979 Out of all your gifts H7311 you shall offer H8641 every heave offering H3068 of the Lord, H2459 of all the best H4720 there, even the hallowed part there out of it.
  30 H559 Therefore you shall say H7311 unto them, When you have heaved H2459 the best H2803 there from it, then it shall be counted H3881 unto the Levites H8393 as the increase H1637 of the threshingfloor, H8393 and as the increase H3342 of the winepress.
  31 H398 And you shall eat H4725 it in every place, H1004 you and your households: H7939 for it is your reward H2500 for H5656 your service H168 in the tabernacle H4150 of the congregation.
  32 H5375 And you shall carry H2399 no sin H7311 by reason of it, when you have heaved H2459 from it the best H2490 of it: neither shall you pollute H6944 the holy things H1121 of the sons H3478 of Israel, H4191 lest you die.
