משנה אויף בראשית 27:34

If he (the husband) wrote to her (his wife), “I have no claim upon you for either a vow or an oath”, he cannot make her swear an oath. However, he may make her heirs and upon those who have done business with her swear an oath. [If he wrote,] “I have no claim upon you for either a vow or an oath nor upon your heirs nor upon those who have done business with you”, he may not impose an oath either upon her or upon her heirs or upon those who have done business with you. However his heirs may impose an oath upon her or upon her heirs or upon those who have done business with her. [If he wrote] “Neither I nor my heirs nor those who have done business with me shall have any claim upon you or upon your heirs or upon those who have done business with you for either a vow or an oath”, neither he nor his heirs nor those who have done business with him may impose an oath either upon her or upon her heirs or upon those who have done business with her.
