Numbers 18:19

"Ought ye not to know that the LORD God of Israel gave the kingdom over Israel to David for ever, even to him and to his sons by a covenant of salt?"

"And every oblation of thy meat offering shalt thou season with salt; neither shalt thou suffer the salt of the covenant of thy God to be lacking from thy meat offering: with all thine offerings thou shalt offer salt."

"And this is thine; the heave offering of their gift, with all the wave offerings of the children of Israel: I have given them unto thee, and to thy sons and to thy daughters with thee, by a statute for ever: every one that is clean in thy house shall eat of it."

"And Moses gave the tribute, which was the LORD'S heave offering, unto Eleazar the priest, as the LORD commanded Moses."

"And thither ye shall bring your burnt offerings, and your sacrifices, and your tithes, and heave offerings of your hand, and your vows, and your freewill offerings, and the firstlings of your herds and of your flocks:"

"Take it of their half, and give it unto Eleazar the priest, for an heave offering of the LORD."

"And of it he shall offer one out of the whole oblation for an heave offering unto the LORD, and it shall be the priest's that sprinkleth the blood of the peace offerings."

"Moreover he commanded the people that dwelt in Jerusalem to give the portion of the priests and the Levites, that they might be encouraged in the law of the LORD."

"And the LORD spake unto Aaron, Behold, I also have given thee the charge of mine heave offerings of all the hallowed things of the children of Israel; unto thee have I given them by reason of the anointing, and to thy sons, by an ordinance for ever."
