'Willing' in the Bible

And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart and with a willing mind; for Jehovah searcheth all hearts, and understandeth all the imaginations of the thoughts: if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever.

And, behold, there are the courses of the priests and the Levites, for all the service of the house of God: and there shall be with thee in all manner of work every willing man that hath skill, for any manner of service: also the captains and all the people will be wholly at thy commandment.
