1 Chronicles 29:14

That we should be able to offer so willingly, i.e. that thou shouldst give us both such riches out of which we should be able to make such an offering, and such a willing and free heart to offer them; both which are thy gifts, and the fruits of thy good grace and mercy to us. Of thine own have we given thee; we return only what we have received, and therefore we do only pay a debt to thee, and do not hereby oblige thee, or deserve any thing from thee.
