Albert Barnes Commentary 1 Chronicles 29:5

"of gold for the [things of] gold, and of silver for the [things of] silver, and for all manner of work [to be made] by the hands of artificers. Who then offereth willingly to consecrate himself this day unto Jehovah?" — 1 Chronicles 29:5 (ASV)

To consecrate his service - This phrase literally means, as noted in the margin, “to fill his hand,” that is, “to come with full hands to Yahweh.” The words contain an appeal to the assembly for voluntary offerings.
