'Voluntary offerings' in the Bible

And they took from Moses every heave-offering that the children of Israel had brought for the work of the service of the sanctuary, to make it. And they still brought him voluntary offerings morning by morning.

Speak unto Aaron, and to his sons, and unto all the children of Israel, and say unto them, Whatever man of the house of Israel, or of the sojourners in Israel, that presenteth his offering for any of his vows, and for any of his voluntary offerings, which they present to Jehovah as a burnt-offering,

besides the sabbaths of Jehovah, and besides your gifts, and besides all your vows, and besides all your voluntary offerings, which ye give to Jehovah.

These shall ye offer to Jehovah in your set feasts, besides your vows, and your voluntary-offerings, for your burnt-offerings, and for your oblations, and for your drink-offerings, and for your peace-offerings.

and thither ye shall bring your burnt-offerings and your sacrifices, and your tithes, and the heave-offering of your hand, and your vows, and your voluntary-offerings, and the firstlings of your kine and of your sheep;

Thou mayest not eat within thy gates the tithe of thy corn, or of thy new wine, or of thine oil, or the firstlings of thy kine or of thy sheep, nor any of thy vows which thou vowest, nor thy voluntary-offerings, nor the heave-offering of thy hand;

And Kore the son of Jimnah the Levite, the doorkeeper toward the east, was over the voluntary-offerings of God, to distribute the heave-offerings of Jehovah, and the most holy things.

Accept, I beseech thee, Jehovah, the voluntary-offerings of my mouth, and teach me thy judgments.

and burn a thank-offering with leaven, and proclaim, publish, voluntary offerings: for this pleaseth you, children of Israel, saith the Lord Jehovah.
