Be just, my lovely swain, and do not take Freedoms you'll not to me allow; Or give Amynta so much freedom back That she may rove as well as you. Let us then love upon the honest square, Since interest neither have designed. For the sly gamester, who ne'er plays me fair, Must trick for trick expect to find.
