'Willingly' in the Bible

of gold for the things of gold, and of silver for the things of'silver, and for all manner of work to be made by the hands of artificers. Who then offereth willingly to consecrate himself this day unto Jehovah?

Then the princes of the fathers houses , and the princes of the tribes of Israel, and the captains of thousands and of hundreds, with the rulers over the king's work, offered willingly;

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

But who am I, and what is my people, that we should be able to offer so willingly after this sort? for all things come of thee, and of thine own have we given thee.

I know also, my God, that thou triest the heart, and hast pleasure in uprightness. As for me, in the uprightness of my heart I have willingly offered all these things: and now have I seen with joy thy people, that are present here, offer willingly unto thee.
