'Willing offering' in the Bible
every man and woman (whom their heart hath made willing to bring in for all the work which Jehovah commanded to be done by the hand of Moses) of the sons of Israel brought in a willing-offering to Jehovah.
And they take from before Moses all the heave-offering which the sons of Israel have brought in for the work of the service of the sanctuary to do it; and still they have brought in unto him a willing-offering morning by morning.
'And when a man bringeth near a sacrifice of peace-offerings to Jehovah, to complete a vow, or for a willing-offering, of the herd or of the flock, it is perfect for a pleasing thing: no blemish is in it;
As to an ox or a sheep enlarged or dwarfed -- a willing-offering ye do make it, but for a vow it is not pleasing.
And his heads, for a willing-offering to the people, to the priests, and to the Levites, have lifted up; Hilkiah, and Zechariah, and Jehiel, leaders in the house of God, to the priests have given for passover-offerings two thousand and six hundred, and oxen three hundred;
and after this a continual burnt-offering, and for new moons, and for all appointed seasons of Jehovah that are sanctified; and for every one who is willingly offering a willing-offering to Jehovah.
