'Willingly' in the Bible

of gold for the [things of] gold, and of silver for the [things of] silver, and for all kinds of work [to be made] by the hands of artificers. Who then offers willingly to consecrate himself this day to Yahweh?"

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, because they offered willingly, because with a perfect heart they offered willingly to Yahweh: 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 as this? For all things come from you, and of your own have we given you.

I know also, my God, that you try the heart, and have pleasure in uprightness. As for me, in the uprightness of my heart I have willingly offered all these things. Now have I seen with joy your people, that are present here, offer willingly to you.
