On Righteousness, Oaths, and Usury (Sources in Early Modern Economics, Ethics, and Law)

This text is a translation of Wolfgang Musculus’ commentary on Psalm 15 and his related appendices on the topics of oaths and usury. In these selections from his expansive exegetical work, Musculus presents a theological exposition of the psalm and gives guidance in matters of enduring relevance for Christian living—particularly how to preserve truth and honesty in one’s relationships, speech, and economic practices.
