1 Chronicles 29:5

the gold for things of gold, and the silver for things of silver and for all manner of work to be made by the hands of artificers, the craftsmen and silversmiths. And who, then, is willing to consecrate his service, literally, "to fill his hand," this day unto the Lord? The meaning is that everyone following the king in his voluntary offering would be making a free-will sacrifice to Jehovah. Each believer, a priest to the Lord, would thus worship by presenting his sacrifice in person.
