'Willing' in the Bible

and Jehovah hath not been willing to destroy the house of David, for the sake of the covenant that He made with David, and as He had said to give to him a lamp, and to his sons -- all the days.

Hezekiah concluded, “Now you are consecrated to the Lord. Come near and bring sacrifices and thank offerings to the Lord’s temple.” So the congregation brought sacrifices and thank offerings, and all those with willing hearts brought burnt offerings.
