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. As many as were willing-hearted - For no one was forced to lend his help in this sacred work; all was a free-will offering to the Lord.
