'Willingly' in the Bible

Then the leaders of the households, the leaders of the tribes of Israel, the commanders of thousands and of hundreds, and the officials in charge of the king’s work gave willingly.

I know, my God, that You test the heart and that You are pleased with what is right. I have willingly given all these things with an upright heart, and now I have seen Your people who are present here giving joyfully and willingly to You.
