According to volume 25 of the Works of Jonathan Edwards, he preached a sermon in January of 1747 on Ezekiel 22:12 with this title: "Subject: the sin of extortion." It is item number 853 in the catalogue (see p. 729 of volume 25). That sermon is not published in volume 25 (which covers 1743-1758 of sermons and discourses), but it might be in the extended works on the Yale website.
