1 Chronicles 29:9

For to their power, I bear record, yea, and beyond their power they were willing of themselves;

Let your heart therefore be perfect with the LORD our God, to walk in his statutes, and to keep his commandments, as at this day.

These things have I spoken unto you, that my joy might remain in you, and that your joy might be full.

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

But I rejoiced in the Lord greatly, that now at the last your care of me hath flourished again; wherein ye were also careful, but ye lacked opportunity.

Therefore, my brethren dearly beloved and longed for, my joy and crown, so stand fast in the Lord, my dearly beloved.

For if there be first a willing mind, it is accepted according to that a man hath, and not according to that he hath not.

My heart is toward the governors of Israel, that offered themselves willingly among the people. Bless ye the LORD.

And when he cometh home, he calleth together his friends and neighbours, saying unto them, Rejoice with me; for I have found my sheep which was lost.

Thy people shall be willing in the day of thy power, in the beauties of holiness from the womb of the morning: thou hast the dew of thy youth.
