'Heave offering' in the Bible

And Azariah, the chief priest of the house of Zadok, spake unto him, - and said - From the time of beginning to bring in, the heave-offering, into the house of Yahweh - to eat and to be full, there hath still been left, even to this abundance. For, Yahweh, hath blessed his people, and, that which is left, is this great plenty.

and brought in the heave-offering and the tithe and the hallowed things, faithfully, - and, over them, as chief ruler, was Cononiah the Levite, and Shimei his brother, next;

And, Kore, son of Imnah the Levite, the door-keeper on the east, was over the freewill offerings of God, - to give the heave-offering of Yahweh, and the most holy things.
