2 Corinthians 8:3

The children of Israel brought a willing offering unto the LORD, every man and woman, whose heart made them willing to bring for all manner of work, which the LORD had commanded to be made by the hand of Moses.

But without thy mind would I do nothing; that thy benefit should not be as it were of necessity, but willingly.

Then the people rejoiced, for that they offered willingly, because with perfect heart they offered willingly to the LORD: and David the king also rejoiced with great joy.

Take ye from among you an offering unto the LORD: whosoever is of a willing heart, let him bring it, an offering of the LORD; gold, and silver, and brass,

The gold for things of gold, and the silver for things of silver, and for all manner of work to be made by the hands of artificers. And who then is willing to consecrate his service this day unto the LORD? consecrate his service: Heb. fill his hand Then the chief of the fathers and princes of the tribes of Israel, and the captains of thousands and of hundreds, with the rulers of the king's work, offered willingly,

Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.

And they came, every one whose heart stirred him up, and every one whom his spirit made willing, and they brought the LORD'S offering to the work of the tabernacle of the congregation, and for all his service, and for the holy garments. And they came, both men and women, as many as were willing hearted, and brought bracelets, and earrings, and rings, and tablets, all jewels of gold: and every man that offered offered an offering of gold unto the LORD.

Now therefore perform the doing of it; that as there was a readiness to will, so there may be a performance also out of that which ye have. For if there be first a willing mind, it is accepted according to that a man hath, and not according to that he hath not.

For it is God which worketh in you both to will and to do of his good pleasure.

Then the disciples, every man according to his ability, determined to send relief unto the brethren which dwelt in Judaea:

Feed the flock of God which is among you, taking the oversight thereof, not by constraint, but willingly; not for filthy lucre, but of a ready mind; which...: or, as much as in you is

For if I do this thing willingly, I have a reward: but if against my will, a dispensation of the gospel is committed unto me.
