Exodus 35:5; Exodus 35:22

5 Take from among you a contribution to the LORD. Whoever is of a generous heart, let him bring the LORD's contribution: gold, silver, and bronze;

22 So they came, both men and women. All who were of a willing heart brought brooches and earrings and signet rings and armlets, all sorts of gold objects, every man dedicating an offering of gold to the LORD.
