“Therefore thou shalt say unto them, When ye have heaved the best thereof from it, then it shall be counted unto the Levites as the increase of the threshingfloor, and as the increase of the winepress.”
King James Version (KJV)
18:28 To Aaron - And to his children, who were all to have their share herein.
18:29 Your gifts - Not only out of your tithes, but out of the other gifts which you receive from the people, and out of those fields which shall belong to your cities. Offer - To the priest. As many gifts, so many heave - offerings; you shall reserve a part out of each of them for the priest. The hallowed part - the tenth part, which was the part or proportion that God hallowed or sanctified to himself as his proper portion.
18:31 Every place - In every clean place, and not in the holy place only.
18:32 Neither shall ye pollute the holy things - As you will do, if you abuse their holy offerings, by reserving that entirely to yourselves, which they offer to God to be disposed as he hath appointed, namely, part to you, and part to the priests.
