'Willing hearted' in the Bible

And they came, both men and women, as many as were willing hearted, and brought bracelets, and earrings, and rings, and tablets, all jewels of gold: and every man that offered offered an offering of gold unto the LORD.

And Hezekiah answereth and saith, 'Now ye have filled your hand to Jehovah, come nigh, and bring in sacrifices and thank-offerings to the house of Jehovah;' and the assembly bring in sacrifices and thank-offerings, and every willing-hearted one -- burnt-offerings.

The willing-hearted of the peoples have gathered together, with the people of the God of Abraham. For unto God belong the shields of the earth: he is greatly exalted.
